Mexico-United States Christmas Tale: From Nochebuena—"Christmas Eve" Flower—to Poinsettia

The Nochebuena [literally, "Good Night"], "Christmas Eve" flower, or poinsettia (Euphorbia pulcherrima) is native to Mexico.  This shrub, capable of growing up to fifteen feet tall (!), can be found in tropical deciduous forests in moderate elevations along Mexico's Pacific Coast south to Guatemala and in some hot, seasonally dry forests in the country's interior.

With its dark green, serrated leaves and upper leaves of red, yellow or marbled with white, the Nochebuena-Poinsettia has become one of the most ubiquitous symbols of Christmas. In various parts of the world it is known as Christmas Star.


The shrubs can grow to 15'

It has a pre-Hispanic heritage. The Náhuatl name is cuetlaxochitl [kuet-la-sóch-itl], which means "leather flower". The Aztecs used the plant in rituals as a symbol of purity and new life for warriors, and they made offerings of it to the Sun to renew its strength.

In colonial times, because of its appearance at Christmastime, the Spanish named the plant "Nochebuena", the Spanish name for Christmas Eve. Beginning in the seventeenth century, the plant became a symbol of the holidays.

The tradition of decorating homes with Nochebuena comes from the U.S. In 1828, Joel Robert Poinsett, the first U.S. minister to Mexico, who was also a physician and amateur botanist, was impressed by its beauty and sent a few plants home.

But it was not until 1909, that the family of Albert Ecke began to cultivate the plant commercially in California, undertaking its controlled breeding and production. The family patented the flower under the name poinsettia. They produced plants of various colors and foliage, each of which they patented, thus controlling a virtual market monopoly into the 1990s.

In Mexico, the Aztecs used parts of the flower to create reddish purple dye for textiles and for medicine. According to the Atlas of Mexican Plants for Traditional Medicine of the National Autonomous University of Mexico (UNAM), it has many medicinal uses related to skin disorders, female ailments and inflammatory processes.

According to information from the Secretariat of Agriculture, Livestock, Rural Development, Fisheries and Food (SAGARPA), Mexico ranks fourth worldwide in cultivated area, and at least 300 hectares [741 acres] are dedicated to growing potted poinsettia plants. The main states where it is cultivated are Morelos, Michoacán, Mexico City, Puebla, State of Mexico, Jalisco, Veracruz, Querétaro, Guanajuato, Chiapas and Guerrero... Spanish original

Green Shoots 5: Ever-Widening Circles of Response to Environmental Threat

Hermann Bellinghausen reports on Mexico's indigenous peoples for La Jornada. Several days ago, his article "Where the Living Jungle Lives" appeared. The story of an outsider's first visit to the community, "Sarayaku: A Journey Into the Heart of the Resistance", includes details and photos that enrich Sarayaku, the Kichwa community described by Bellinghausen. Links to relevant articles are provided below this translation.

"Where the Living Jungle Lives"
Hermann Bellinghausen,
One afternoon late in 2011, while sharing manioc beer under an umbrella a few yards from the Bobonaza River [flows into the Amazon] in Ecuador's Amazon jungle, José Gualinga wondered, What is the "living forest" (Kawsak Sacha in Kichwa, or Quechua). Here's how he answered his own question:
"A space of beings where we people elevate our physical, psychological and psychic emotions. For example, in August most of the people move into the jungle, not in a community, but into the jungle, in little houses deep in the interior. There the children, women, everyone, re-create, pick up their life. They go to see the Masanga, the mysteries. This strengthens you and makes brotherhood, unity and respect for the natural world" (Ojarasca, October 2011).
At that time, Gualinga presided over Sarayaku's Governing Council. Before and after, he has taken on various responsibilities representing his people in national organizations and before the world. The Sarayaku defeated an oil company and the government of Rafael Correa himself. They are living proof that it can be done. Bearing the voice of his people, Gualinga has traveled. He does not ignore the essentials of the global environment, or the poisonous honeys of the "first world" or the stinky breath of the leadership circles in Quito [Ecuador], but he knows that in his place life is better without poisons and in harmony with the natural world.

The Kichwas of Sarayaku pulled themselves together. They let the land speak, and they live as she says:
"It is sacred territory, one must not destroy it. The living jungle is also the place where the shamans and elders transmit their knowledge—the science of the jungle, how to know the trees, plants, fish, animals, orient yourself, dream, have visions. This is our science, the relationship with this world. A language of communication with the animals."
Gualinga spoke of the Amazonian indigenous project that goes against the grain of the capitalism that has historically ignored the indigenous people and their existential choices. It is long-term; it is for today and for when we die. This future defines the present. Not the opposite, like the non-neoliberal project that subjects the future to the present. Gualinga confided:
"This proposal that all nationalities of the center-south Amazon region are developing—the Kichwa territory is one border, and the territory extends all the way to the Achuar and Shuar territory. The indigenous territory is five million hectares [12.4 million acres; 19,305 square miles]. The northeastern jungle, Sucumbios, Orellana are already affected, but here the jungle remains well protected."
Now, four years later, the people of the Amazon march once again in the Ecuadorian distances [outside the jungle] to demonstrate their rights and their principle of existence in resistance to the populist-extractivist government of Correa (who has already had to legislate on the rights of Mother Earth).
"As the government expands the oil blocks, we propose declaring the living jungle to be sacred of the beings, where our life is constituted. We propose plans of life: managing the natural resources according to our vision grounded in a fertile earth, applying the knowledge of the peoples and the social behavior that make Sumaj Kawsay (Good Living in Kichwa; in Spanish Buen Vivir). Within that [proposal] we are going to use the natural resources for education, health and our own economy. The platform, the great vision, is to maintain the Sumaj Kawsay, where the natural world is not contaminated but free."
This way of thinking is winning significant battles. In Argentina, impressed by the examples of Bolivia and Ecuador, a Supreme Court Justice wrote "La Pachamama y el humano", Mother Earth and the Human Being (published by Mothers of the Plaza de Mayo, 2012). Justice Eugenio Raúl Zaffaroni undertakes a legal, philosophical and humanistic review, from Kant to Monod, of man's relationship with the natural and animal world. Zaffaroni calls for working "intelligently" in the search for a "friendly coexistence" between man and La Pachamama, Mother Earth. On page 12, he writes that if they continue preying on the rivers, mountains and animals that live there,
"the planet is going to continue living. It is not going to end, but we are the ones who are not going to continue living, we human beings."
The most lucid indigenous peoples in South America are moving forward on a risky, but possible project. They have managed to set legal limits .... In a 2014 interview with Lobo Suelto [Unleashed, Loose Wolf], Silvia Rivera Cusicanqui declared:
"What we do is transform ourselves into a collective will of 'doing'. We always project ourselves toward the outside as collective wills that break the barrier between the manual and the intellectual."
In her criticism of the government socialisms that, including Bolivia, just don't understand the indigenous peoples, the relentless Aymara thinker said:
"We are no longer alone, since also accompanying us are a whole lot of critters and the Earth." ... 
Are we speaking of a dimension more humane than democracy? Spanish original

There is no more fitting way to close this post than by presenting the ambitious campaign sponsored by AVAAZ to establish in the Amazon River Basin the world's largest environmental preserve: 135 million hectares [333,592,265 acres; 521,238 square miles] of Amazon jungle. That's more than twice the size of France! The petition states:
"But it won’t happen unless Brazil, Colombia and Venezuela’s leaders know the public wants it. That’s where we [AVAAZ] come in. 
"Colombia has just said it is on board. Now, if we create a huge global push to save the Amazon and combine it with national polls in all three countries, we can give the Colombian president the support he needs to convince Brazil and Venezuela. All three leaders are looking for opportunities to shine at the next UN climate summit. Let’s give it to them.
"The Amazon is vital to life on earth—10% of known species live there, and its trees help slow down climate change by storing billions of tons of carbon that would otherwise be in the atmosphere. Experts say this reserve would be a total game-changer for stopping rampant deforestation. Sign the petition now, when we reach 1 million signers, indigenous leaders will deliver our petition and polls directly to the three governments."
* * * * *
Let me give the last word to Paul Hawken:
When asked if I am pessimistic or optimistic about the future, my answer is always the same: If you look at the science about what is happening on earth and aren’t pessimistic, you don’t understand data. But if you meet the people who are working to restore this earth and the lives of the poor, and you aren’t optimistic, you haven’t got a pulse. 
What I see everywhere in the world are tens of millions of ordinary people willing to confront despair, power, and incalculable odds in order to restore some semblance of grace, justice, and beauty to this world.

Green Shoots 4: Worldwide Social Movement Is Afoot, Under Radar of Mainstream Culture

When we moved to Mexico seven years ago, I recall idly wondering how we might be affected by living long-term outside the United States. For the first few years we were caught up in building some master of Spanish and becoming acquainted with the endlessly fascinating, complex levels of Mexican culture. We had neither time nor emotional space for thinking about it.

During the three years we lived in Pátzcuaro, we were especially attracted to Purhépecha culture. That interest, in turn, led us to explore in greater depth what anthropologists more broadly call Mesoamerican culture. We visited many, if not most, of Mexico's southern archaeological sites, all the while becoming increasingly aware of similarities between the linguistic and cultural groups we visited. Regardless of location, these groups share two major themes: a common cosmovisión, or worldview, and their profound relationship to la naturaleza, the natural world.

Meanwhile, disheartened by all that is not being done to deal with climate change, I had come to wonder if the relationship forged with Mother Earth by Mexico's indigenous peoples might be unique to Mexico. Fortuitously, I came upon the work of Paul Hawken, environmentalist, entrepreneur, and author whose influential writings have shaped corporate sustainability. Prior to the 2007 release of his book Blessed Unrest, the environmental magazine Orion published an article adapted from the book.

In that 2007 piece, Hawken relates that over the last fifteen years he's given close to a thousand talks about the environment. Afterward, people would gather to talk, ask questions and offer their cards:
The people offering their cards were working on the most salient issues of our day: climate change, poverty, deforestation, peace, water, hunger, conservation, human rights, and more. They were from the nonprofit and nongovernmental world, also known as civil society. 
They looked after rivers and bays, educated consumers about sustainable agriculture, retrofitted houses with solar panels, lobbied state legislatures about pollution, fought against corporate-weighted trade policies, worked to green inner cities, or taught children about the environment. Quite simply, they were trying to safeguard nature and ensure justice.
Arriving home from a trip, Paul would take out the cards, look at the names and logos, and reflect on their various missions. Then he'd put the cards in paper bags. Tellingly, he writes: "I couldn't throw them away."

Eventually, Hawken got curious: did anyone know how many organizations there were? His initial curiosity evolved into a "hunch that something larger was afoot, a significant social movement that was eluding the radar of mainstream culture."

Government tax census records in some countries enabled him to extrapolate the number of environmental and social justice groups. At first, Hawken estimated the number of environmental groups to be 30,000 worldwide — a number that swelled to 100,000 when he included social justice groups:
"Historically, social movements have arisen primarily because of injustice, inequalities, and corruption. Those woes remain legion, but a new condition exists that has no precedent: the planet has a life-threatening disease that is marked by massive ecological degradation and rapid climate change. It crossed my mind that perhaps I was seeing something organic, if not biologic. Rather than a movement in the conventional sense, is it a collective response to threat?" 
Hawken has a lot more to say—let me highly recommend Blessed Unrest—but consider these:
"After spending years researching this phenomenon, including creating with my colleagues a global database of these organizations, I have come to these conclusions: [1] this is the largest social movement in all of history; [2] no one knows its scope; and [3] how it functions is more mysterious than what meets the eye. 
"What does meet the eye is compelling: tens of millions of ordinary and not-so-ordinary people willing to confront despair, power, and incalculable odds in order to restore some semblance of grace, justice, and beauty to this world."
Hawken concludes the Orion article with these prophetic words:
THERE IS FIERCENESS HERE. There is no other explanation for the raw courage and heart seen over and over again in the people who march, speak, create, resist, and build. It is the fierceness of what it means to know we are human and want to survive. 
This movement is relentless and unafraid. It cannot be mollified, pacified, or suppressed. There can be no Berlin Wall moment, no treaty-signing, no morning to awaken when the superpowers agree to stand down. The movement will continue to take myriad forms. It will not rest. There will be no Marx, Alexander, or Kennedy. No book can explain it, no person can represent it, no words can encompass it, because the movement is the breathing, sentient testament of the living world. 
And I believe it will prevail. I don’t mean defeat, conquer, or cause harm to someone else. And I don’t tender the claim in an oracular sense. I mean the thinking that informs the movement’s goal — to create a just society conducive to life on Earth — will reign. It will soon suffuse and permeate most institutions. But before then, it will change a sufficient number of people so as to begin the reversal of centuries of frenzied self-destruction. 
Inspiration is not garnered from litanies of what is flawed; it resides in humanity’s willingness to restore, redress, reform, recover, re-imagine, and reconsider. Healing the wounds of the Earth and its people does not require saintliness or a political party. It is not a liberal or conservative activity. It is a sacred act
In Hawken's view, three intertwining roots make up this inchoate worldwide movement: the environmental and social justice movements, for sure, but — central to our interests — the resistance by indigenous cultures to globalization.

In Mexico, Miguel Concha, National Autonomous University of Mexico (UNAM) professor and a long-time, highly respected human rights advocate, lays out the challenges clearly and succinctly: "Mexico's Ordinary People Struggle for Life, Land, Water and Work". More specifically, the Zapatista movement in Chiapas probably enjoys the broadest international recognition, but other movements are just as far-reaching and important. To name just two: communal actions by the Yaqui Tribe in Sonora (against diversion of water from the Sonora River—in violation of indigenous water rights—for industrial purposes); and community actions taken in seemingly lesser places like Cherán, Michoacán (Purhépecha indigenous community successfully claimed its constitutional right self-government under traditional Uses and Customs and, hence, to defend its hereditary lands from illegal logging by organized crime).

Hawken's idea of grassroots activism isn't a new theme for Jenny's Journal. In 2010, we wrote a three-part series titled 'Green Shoots' (see below) that explored the notion of community that is at the very heart of indigenous cultures all over the world. But a healthy sense of community is by no means restricted to indigenous cultures.

Green Shoots 3 recaps highlights of Bill Moyers' conversation with Grace Lee Boggs, Ph.D. in Philosophy from Bryn Mawr and a civil rights activist in Detroit for more than fifty years. Ninety-one years-old when she spoke with Moyers (she died recently, October 5, 2015, at age 100), Boggs talked about the cultural revolution she saw brewing in our country at the grassroots level. When Moyers asked her what advice she had for young people, she replied,
"Do something local and specific—it doesn't matter what it is, just start."
Echos of Paul Hawken—actually, Hawken would probably say that what's happening in Detroit is yet another spontaneous human expression in response to the global environmental threat. If they're not already on it, Hawken would certainly add Detroit's grassroots community organizations to his ever-growing list—now conservatively estimated at 130,000—of organizations contributing to worldwide Blessed Unrest.

Indigenous Wisdom and Clouds in Mexico ... and Alaska!

Today's weather forecast for Mexico is:
"Heavy rains are predicted across the entire country, including the Valley of Mexico" — Translation: Mexico City. 
For all the clouds we've seen in the last six weeks, we could have moved to Seattle!

Neither Reed nor I do very well with gray skies, but yesterday the air was clear, so I leaned out the bedroom window to check on Ajusco Volcano to the southwest. Here's what greeted my astonished eyes!

(Photo: Reed with my little Canon)

I have been on the lookout for this effect for at least five years. Why? An anthropologist studying the indigenous people of Mexico was told by his informants that clouds rise up from the mountains. Without success, he tried explaining scientifically how clouds are formed.

Then one day, he saw a formation like this one, and he had to admit that the traditional version was based on an understandable interpretation of their observation.

But believe it or not, la naturaleza, Natural World, wasn't quite done with me yet. On the same day, I opened up Facebook only to discover this photo taken by a friend who lives 25 miles north of the Arctic Circle in Kobuk, Alaska:

Camp Taiga, Kobuk, Alaska - Click to Enlarge!
(Photo: Gregory Jurisch)
Never mind the incredible cloud formation, I can't get over the flecks of white flowers, which seem to reflect the spots of snow remaining on the mountains.

Here's another of Greg's photos taken June 20 and captioned:
"Today's Weather Report, 'Hot Air Rising'."
"Hot Air Rising" at Camp Taiga, Kobuk, Alaska
(Photo: Gregory Jurisch)

Is that what's happening? Hot air rising off the mountains? Yet again, America's original peoples have it right. By America, I mean in its true sense of all residents of North, Central and South America.
Note: I just googled the phenomenon and found this wonderful diagram and explanation at Windows to the Universe:
When wind blows across a mountain range, air rises and cools, 
and clouds can form.
"Some clouds form when air encounters a mountain range or other types of terrain. When this happens, the air will rise and cool, but this cooler air is no longer able to hold all of the water vapor it was able to hold when it was warm, so the extra water vapor begins to condense out of the air parcel in the form of liquid water droplets that form a cloud."
Thus confirming what the indigenous people told the skeptical anthropologist:
"The clouds rise up from the mountain."
And, of course, the mountains are sacred not just to Mexico's indigenous peoples, but to indigenous people all over the world.

It's also important to remember that Mexico City is at 7,000 feet [2,133.6 meters]; Ajusco Volcano is 12,893 feet [3,930 meters], with a prominance of 1,217 3992.782 which means that warm air is rising 3,992 feet [1,217 meters] along the volcano's flanks. Hence, it makes sense that warm air would condense as it rises along the flanks of high altitude mountains whereas it condenses at the top of mountains rising from sea level.

Then this morning, I wakened to the first sighting in two weeks of our volcanoes to the East: Iztaccíhuatl and Popocatéptl.

Ending on an upbeat for me means Mexico full of color. So here's the image of Iztacc and Popo I captured on a clear, clear morning:

And another of Ajusco Volcano I captured on an exceptionally clear day during the dry season.

Over the last twenty-four hours, the natural world has treated me to quite an adventure!

P.S. More confirmation of the phenomenon comes by way of the photo I took today at sunset of a cloud 'rising up from' the flank of Iztaccíhuatl Volcano. Mother Nature never ceases to amaze and delight!

The Enduring Power of Mexico's Natural Forces

View From The Balcony: 
Shades of Gray Cover the Countryside While Popo Puffs Away

After a delightful visit to Chicago to play with our grandchildren, we arrived back in Mexico City on September 5th only to encounter more than a week of cloudy, cold and extremely wet days.

Last weekend, September 14, Mexico City found itself sandwiched between Hurricane Ingrid arriving from the Gulf to batter the coast of Veracruz; and Tropical Storm Manuel rolling in from the Pacific to wreak havoc along the Pacific Coast. 

The silver lining is that on Monday the 15th after the storms, we were able to see the volcanoes for the first time in weeks. Thought you all might enjoy them in all their shades of gray highlighted by a touch of peach. Tomorrow's forecast: More heavy rain. Sigh....

I've written a lot about the impact of natural forces on Mexico's original peoples, but this week's storms have brought the topic home in a dramatic way. The juncture of multiple tectonic plates creates a volcanic axis that runs like a belt across Mexico's mid-section. It's hard to believe the number of both extinct and active volcanoes found along that axis. Mexico's geology also makes the country vulnerable to hurricanes that arrive both from the Pacific and Atlantic Oceans, although not usually at the same time!

This weekend's twin storms prompted us to reflect again on the cultural impact of the wind, including hurricanes, on Mexico's original peoples. When we began taking stock, we realized that the symbols are widely dispersed. Cuicuilco is one of the earliest settlements in the Valley of Mexico (Mexico City). Sometime between 150 and 200 Common Era, Cuicuilco was destroyed when Xitle, a nearby volcano, erupted. Cuicuilco's circular pyramid was dedicated to Ehécatl, god of wind.

Cuicuilco's spiral retaining walls also served as the pyramid's staircase

Also in Mexico City, but from the much later Aztec period, is the archaeological site at Tlatelolco, which has a temple to Ehécatl-Quetzalcóatl. Ehécatl is Quetzalcóatl's manifestation as the wind.

On the back wall of the main pyramid at Tlatelolco is this symbol for Ehécatl-Quetzalcóatl; the spiral represents the hurricane's swirling winds.

Detail: Main Pyramid at Tlatelolco, Mexico City

Next we go to the Templo Mayor (Great Temple) at Tenochtitlán [Historic District in Mexico City], where more representations of the spiral winds are to be found.

Templo Mayor, Mexico City

In Veracruz on the Gulf of Mexico, we have visited El Tajín (thunder, hurricane, lightning in the Totonaca dialect). The symbolism of hurricanes is visible in the greca escalonada, which archaeologists believe was originally in the form of a spiral (hurricane) before assuming its now-familiar geometric form.
Greca escalonada was probably a spiral before it took this geometric form.

Also in Veracruz, we saw the tradition of the voladores (flyers), whose descending spiral 'dance' imitates the hurricane's spiral wind and, in so doing, evokes the form of the Ollin, or Life-Force.

Voladores (Flyers) from Papantla evoke the Ollín
 in the form of the swirling winds that form Hurricanes.

The rains were key to the survival of the original peoples. In fact, an oft-quoted Mexico dicho (saying) is, "El agua es la vida" ("Water is life").

If anyone doubts the enduring strength of la naturaleza (natural forces) in Mexican culture, consider this: today I was chatting with a quite-modern Mexican friend. The conversation naturally shifted to the devastating floods and landslides attacking Mexico's people along both coastlines. She became quite animated, almost agitated, as she urgently insisted,
"It is the strength of la naturaleza; the Aztecs knew...."
Postscript: After reading this post, a long-time geologist friend of mine wrote to give me this quote by Will Durant (1885-1981) American writer, historian, and philosopher:
"Civilization exists by geological consent, subject to change without notice."

Here Comes the Sun!

16th century Franciscan chapel in Tzintzuntzan, Michoacán
Photo: Reed
Today I want to write about the Sun. Like other agrarian societies around the world, Mesoamerica's original peoples relied on their knowledge of the Sun's path across the heavens to mark the seasonal changes that cued them when to perform specific tasks, such as when to plant and harvest; when to lay in winter supplies, etc.

If it weren't for Reed's insatiable curiosity about the heavens, it's unlikely that I would even be paying attention. Since he was asked to explain, more or less patiently, the concepts multiple times before I finally understood them, this post is lovingly, gratefully, dedicated to him.

Tonight we went out for dinner at a Chinese Buffet in our neighborhood, which was remarkably good. At dinner, we were casually chatting. I believe I may have thanked him for his help, which prompted this reply:

Reed's Reflection: "It's really about getting back in touch with a natural process that we moderns have mostly lost. People once told time by the Sun. Now we may note Sunrise and Sunset, but instead of checking the Sun's position we look at our watches."

Reed isn't an Eagle Scout for nothing! It's going to be fun watching him induct our physically and mentally active, extraordinarily curious grandson into all these natural processes. But I digress.

Back to Basics

Three of the most significant imaginary lines running across the Earth's surface are the Equator, the Tropic of Cancer, and the Tropic of Capricorn.

The Equator is the longest line of latitude on the Earth, i.e., where the Earth is widest in an east-west direction. The Equator is also where:
  • Day and night are equal every day of the year—day is always twelve hours long, and night is always twelve hours long, but the Sun is
  • Directly overhead at noon on the two Equinoxes—near March 21 and September 21.
At 23.5 degrees North, the Tropic of Cancer is where the Sun is directly overhead at noon on the June 21 Solstice (longest day of the year in Northern Hemisphere). The Tropic of Capricorn (23.5 degrees South of the Equator) is where the Sun is directly overhead at noon on December 21, Solstice (longest day of the year in the Southern Hemisphere).
Egghead Note: The word solstice is derived from the Latin sol (sun) and sistere (to stand still), because at the solstices, the Sun stands still in declination; that is, the seasonal movement of the Sun's path (as seen from Earth) comes to a stop before reversing direction.
Keep in mind that the Equinoxes occur when the Sun is directly over the Equator; and night and day are more or less equal (12 hrs: 12 hrs) around the world (March 21 and September 21). Perhaps even more significantly, the Equinoxes represent the moment when the Sun passes over the Equator from Northern to Southern Hemisphere, or vice versa; thus, it can be observed that the Equinoxes herald important seasonal changes. "The Tropics" are defined as the area bounded by the:
  • Tropic of Cancer, which passes just north of Havana, Cuba, and runs slightly north of Mexico's mid-section out the the southern tip of Baja California before heading out across the Pacific Ocean; and the 
  • Tropic of Capricorn, which passes through Chile, Argentina, Paraguay, Brazil) in the south. 
Tropic of Cancer runs just north of Havana, Cuba, then across
Mexico to the southern tip of Baja California. Mexico City is the
Red Dot in the middle of the country surrounded by the
State of Mexico (turquoise, horseshoe-shaped). (CLICK to Enlarge)

The Tropic of Cancer is marked on one of Mexico's federal highways. Because of a slight annual progression in the tilt of the Earth's axis, the Tropic of Cancer actually shifts slightly every year. Signposts in the photo document this shift from 2005-2010.

Zaragoza-Victoria Federal Highway 83 (Vía Corta) at Kilometer 27+800.
This is the only place on a Mexican Federal Highway where the
Tropic of Cancer is marked with absolute precision, and where the
annual drift (2005-2010) is also precisely marked.

The seasons of the Northern and Southern Hemispheres are mirror images of each other, which means that:
  • June 21 Solstice is: 
  • Summer Solstice (longest day) in the Northern Hemisphere; and 
  • Winter Solstice (shortest day) in the Southern Hemisphere.
  • December 21 Solstice is:
  • Winter Solstice (shortest day) in the Northern Hemisphere; and 
  • Summer Solstice (longest day) in the Southern Hemisphere.
These solar effects are most pronounced at the Arctic and Antarctic circles. For example, 
  • March 21 Equinox at: 
  • Arctic Circle ('North Pole') marks the approach of six months of near continuous daylight, while at the
  • Antarctic Circle ('South Pole') marks the approach of six months of near continuous darkness.
  • September 21 Equinox at:
  • Arctic Circle marks the beginning of six months of near continuous darkness, while 
  • Antarctic Circle marks six months of near daylight.

Mexico City

At 19 degrees 26 minutes north of the Equator, Mexico City is just 4 degrees south of the Tropic of Cancer, which means that the Sun is directly over Mexico City twice: once on May 17 (heading north) before the Summer Solstice then again on July 25 after the Solstice, as the Sun begins its return trip south.


Egghead Note #2: Reed researched the local dates of the two zeniths: May 17 and July 25 over Mexico City, then he added, "We have to remember these dates, so next May 17 we can take a picture to show absolutely no shadow." 
A mere heartbeat later, he asked, "Do you remember in Pátzcuaro how I took the candlestick outside to our patio and waited for its shadow to disappear? The candlestick was so thin that it was perfect ... like a Sun Dial."
Then this: "Do you remember my telling you about the guy in Connecticut who made Sun Dials calibrated to the specific location of the property where it was to be installed?" 
Quiet for a moment, he then added thoughtfully, "I don't know how a Sun Dial would be made for Mexico, since the Sun's path is so far North at this time of year...." 

I am writing this post on August 6th. Yesterday we were out in the noonday sun enjoying Mexico City's Historic Center. Waiting for a light, Reed suddenly noticed that we were pretty much standing on our own shadows.

Because the Sun is always high in the sky, clearly differentiated seasons aren't characteristic of "The Tropics". Temperature differences instead depend on altitude. At sea level, it's very hot and humid. In the mountains, such as here in Mexico City at 7,000 feet, the climate is generally quite temperate. Hence the popular saying,
"It's always spring in Mexico City."

Tracking Sunrise From Our Balcony

At the time of the Equinoxes, the Sun rises due East and sets due West. But what is peculiar to us transplanted Northerners is that as the Sun continues its Northerly path after the Vernal Equinox, not only does it rise more and more to the North, but it stays in the North throughout the day—a distinctly disorienting sensation.

This sunrise photo was taken on June 25, five days after the Summer Solstice [June 20, 2013]. The billboard at the right marks Due East; that is, the Sun rises behind the billboard at both Equinoxes.

Around the World: Fiestas Occur on Seasonal Markers

In all parts of the world, original peoples have celebrated the solstices and equinoxes that marked the changing seasons. For millenia, festivals have fallen on or around these four seasonal markers; for example:
  • Christmas (Winter Solstice);
  • Easter (Vernal-Spring Equinox on Jewish Lunar Calendar);
  • Midsummer (Summer Solstice celebrated in Scandinavian countries);
  • Rosh Hoshonna and Yom Kippur (Autumnal-Fall Equinox on Jewish Lunar Calendar).
The halfway points between Solstice and Equinox have also traditionally been celebrated; for example:
  • Candlearia (Presentation of Jesus in the Temple Forty Days After His Birth) on February 2, which is also the date of the Purhépecha and Aztec New Year (Candlearia in Mexico City);
  • May Day (England) at Midpoint between Vernal Equinox and Summer Solstice;
  • Cruz Verde (Green, or Holy Cross) on May 2-3, which coincides with the planting season in Mexico just ahead of the rains; and
  • All Saints and All Souls Days celebrated at Mid-Fall, November 1-2, also Dia de los Muertos, which was probably originally celebrated in mid-August before it was moved to coincide with the Catholic Liturgical Calendar.

Mexico's original peoples were remarkable astronomers, capable of aligning pyramids and other buildings with the Sun's position at key solar moments. Several of Jenny's Posts describe these phenomena, for example:
  • Mesoamerican God-Kings as City Planners.
  • Xochicalco's Engineers and Scientists (Morelos): Twice each year on May 14/15 and July 28/29, the sun reaches its zenith, directly overhead; at these astronomical mid-days, a very strong ray of sunlight passes through the narrow chimney shaft in the ceiling of the observatory to the cave's floor (see vivid photos), and religious ceremonies were held in the cave to mark this solar event.
  • Tlaxcala State: Cacaxtla Presents Cultural Puzzle: The pyramid at Cacaxtla is so positioned that on September 29 (local Equinox), from the pyramid's highest level, the sun would be observed to rise directly from the crater of the Matlacuéitl volcano; that is, from the mouth of the goddess of vegetation.
  • Teotihuacán I: 'City Where the Gods Are Made' describes how the Great Stairway of the Pyramid of the Sun faces a westerly point on the horizon where the Pleides constellation appears directly in front of it. In late May, before sunrise on the day the sun passes its zenith, the Pleides makes its first annual appearance above the horizon at Teotihuacán. It is believed that this appearance cued the ruling elites to begin organizing the people for the annual agricultural season. 
  • Teotihuacan II: The Shape of Time and Space describes how the urban design incorporates what became known as the Mesoamerican cosmovision.
On the Yucatán Peninsula at Chichén Itzá, the Pyramid of Kukulkán (Plumed Serpent of the Maya) is so constructed and oriented to the Sun that at the Equinoxes (March and September), the play of sunlight and shade creates seven triangles that represent the image of the serpent-god Kukulkán descending to the earth and connecting with its sculpted head at the base of the staircase.
The pyramid is oriented (top to bottom) North-North-East, South-South-West; and East-South-East, West-North-West, which at the Spring and Autumn Equinoxes creates the effect of the serpent-god descending the staircase (over the course of 45 minutes) at Sunset. Bottom left text: Puesta de Sol (Sunset)
For the Maya, the descent and arrival of the serpent-god signified a higher order to begin agricultural activities in advance of the approaching rainy season (March being the month for planting corn in the region).  This 5-minute professional UTube video tours the Pyramid of Kukulkán and shows the image of the serpent "descending" the staircase to connect with to its head of stone resting at the staircase's base.

Mexico: "How Can We Diagnose Popocatéptl's Gastritis?" - UNAM Volcanologist

Last night NPR ran a short piece on Popocatéptl's activity. Today (05/14/2013) a short piece appeared in La Jornada that gives a succinct summary of the science behind Popo's activity. Besides, the title proved to be irresistible. Here's my translation.
La Jornada: Emir Olivares Alonso

Mexico City - With average emissions of 6,000 to 8,000 tons per day, and about 200,000 tons expelled during outstanding eruptions, Popocatepetl is one of five volcanoes in the world that emit the highest levels of sulfur dioxide.

So says a study undertaken by a team of scientists from the Institute of Geophysics of the National Autonomous University of Mexico [UNAM], who have for years monitored emissions of carbon dioxide and sulfur. The purpose of this monitoring is to understand its role in different types of eruptive  episodes, reported Hugo Delgado, researcher at the Department of Volcanology at the UNAM.

Monitoring data show that between 1994--the year in which Popo last erupted--and 2008, the volcano released 30 megatons of gases, and the trends indicate that it will register, at least, another five year period of intense activity.
"The good news," he said, "is that while the gases vent efficiently as they are today, there will be no serious problems."
Equipment for measuring, detecting and monitoring the concentration of gases around the colossus was installed for this project.

Scientific Network
This network consists Tlamacas, Chipiquixtle, Colibrí and Cruz Blanca stations that monitor the volcano 360 degrees around. The scientist explained that emissions are monitored from these four stations, which cover an area of ​​500 square kilometers located in the states of Puebla, Mexico and Morelos. Different methods are used to determine the concentrations of sulfur dioxide and carbon.

Delgado Granados emphasized that the gases play a primary role in the explosive activity of volcanoes. The study of how they are emitted and their trajectory inside provides data on whether or not the eruptions will be explosive, he explained during the talk "How Can We Diagnose Popocatéptl's Gastritis?" given in the auditorium of the Institute of Geophysics Tlayólotl.

The volcanologist commented that, at any given moment, volcanoes emit lava streams and suddenly change their eruptive style to 'explosive' , a phenomenon in which the gases act as the engine of the process, whose origin is still debated by experts.
"In Popo's case, there is controversy about whether [explosive episodes] are caused by hot material that evaporates the limestone rocks or by the magma beneath the volcano. It is a puzzle that must be solved in order to improve explanations of what actually takes place."

Mexico: Popocatéptl's Eruptions Are "Part of the Countryside" Say Neighbors Living On Volcano's Flanks

Popocatéptl's increased activity has put the volcano in the local news. One expert said that his behavior now is similar to what occurred before his last eruption in 1994. So here's the latest information based on my translation of a CNN Mexico article that appeared today. Links are to stories that CNN reporter Elvia Cruz filed, and I translated, last year at this time.

Santiago Xalizintla, Puebla - For José Cortés Agustín, listening to the roar of the volcano Popocatépetl is common. Observing the launch of incandescent material at night, "is part of the beautiful landscape" of his community, Santiago Xalitzintla, a town located less than twelve kilometers [7.5 miles] from the crater.

This Sunday as authorities prepared to evacuate residents near Don Goyo, as the volcano is also known, if it becomes necessary, the 75-year-old continued his normal activities.
"I would rather die here (in Xalitzintla) than leave. It frightens those from the city. The fear does not exist over there, he (Popocatépetl) would not hurt us. He gives us beautiful images so there is no reason to be frightened. No one can predict the day of his eruption (...) They say on the news that there is to be an alert, but his tremors and thunder are part of his business and also of those who live near him," he tells CNN México.
This weekend the Civil Protection "alert" went from Yellow-Phase 2 to Yellow-Phase 3, which means explosions of growing intensity with possibilities of pyroclastic flows--a mixture of gases and hot solids--of moderate range, according to the National Commission for Disaster Prevention (CENAPRED).

In the predawn hours of Sunday morning, the government of the state of Puebla, in the center of Mexico, implemented the Popocatépetl Operation Plan, which means outfitting shelters, the deployment of at least 2,000 emergency crew to the communities closest to the volcano to be prepared in case they have to evacuate the residents.

The volcano is located on the border of the states of Puebla, Mexico and Morelos.

According to the official report, the three communities closest to the crater that would have to be evacuated are San Pedro Benito Juárez, Atlixco, San Nicolás de los Ranchos and Santago Xalitzintla, where more than 11,000 people live.

"We are prepared for everything"

Nestor Torres, who has spent twenty years teaching in the Benito Juárez Elementary School in the village of Santiago Xalitzintla, agrees with José: living on the slopes of Popocatépetl, "does not present a problem".

The 48-year old teacher believes that now the people of this town are "more prepared" in case they have to evacuate.
"The families know that when the bells ring, they have to gather on the plaza in order to be taken to shelters. What must be recognized is that there are stubborn people who would not accept leaving their homes."
Nestor recalls the last time Popocatépetl erupted in December 1994.
"At that time, we were definitely frightened. My students weren't sure what to do, and neither was I. I just remember that the Army came and took us to a hostel. Everyone was scared. The people said that the end of the world had arrived. Fortunately, there were no losses to mourn. Now, we are all very used to Popo's noises", he told CNNMéxico.
He adds that the tremors caused by Don Goyo, shake "very strongly" the windows of the classrooms where he teaches, but that does not interrupt classes.
"At school we are prepared for any contingency. In case of expulsion of lava, ash, stones, the children know how to evacuate and get to the hostel at the high part of Xalitzintla," Araceli Jiménez, teacher responsible for civil protection at Benito Juárez Elementary School.
The high activity that Popocatépetl has sustained since last Tuesday should not be minimized either by the authorities or by the population, says volcanologist, Alejandro Rivera Domínguez.

Right now the volcano presents "a stage of interior pressure followed by forming a dome"; thus, he expects that the expulsion of ash, incandescent material and light stones would continued in the next few hours, or even weeks, says the specialist.
"There is a serious danger that small dense clouds of hot ash and might reach populated areas, so it is important to be vigilant," he says.
The Tradition of Don Goyo

According to the tiempero, Antonio Analco, Popocatépetl has told him that he will not erupt. The tiempero is the person chosen ... to talk with the volcano. He had his last "encounter" with Don Goyo on May 3, when the volcano told him that there will not be major danger.
"He also told me that so much movement bothers him. He doesn't like it that you are afraid. So much commotion by the government and the journalists make him nervous," he says.
The 68-year old man has the belief that Don Goyo will inform him through "a dream" at what point "he will seriously wake up" but "not right now that he only throws ash and lava."

In order to ask the volcano "not to misbehave", Analco says that in the first three days of May, a group of people from Xalitzintla repeated the ritual they did a year ago: they brought a charro suit, band music, mole with turkey meat, bread, fruit, bottles of tequila and candles.
"It is true that we are used to living with him, and every year we ask him that our life together may continue to be healthy," says the tiemperoSpanish original
Jenny's Postscript

The tiempero Antonio Analco may be on to something. According to volcanologist Hugo Delgado Granados and other experts from the UNAM (National Autonomous University of Mexico), so long as the volcano continues to spew gases, "there will not be serious problems" [reported today in the weekly magazine Proceso, 05/13/2013].

Travel Journal: 'Thank you' to Uruápan, Michoacán

The natural beauty of the State of Michoacán is legendary. Mexicans themselves speak of Michoacán as the 'soul of Mexico'. So I was enchanted when a friend who lives in Zirahuén, close to Pátzcuaro (where we lived for three years before moving to Mexico City), forwarded a 'thank-you' letter that appeared in the local newspaper.

The writer had visited friends in Uruápan, a city whose lower elevation puts it at the edge of the Tierra Caliente (hot lands, more tropical vegetation) of Michoacán. Nothing would do, of course, but for me to translate it, which I did several months ago. Disgracefully, I've somehow misplaced the link to the original Spanish. Here it is, with apologies to the original writer, and with the hope that I can make amends with the photographs.
"I went to Uruápan, and returned uruapanizado'd. How beautiful is this place amidst wonderful gardens, the vast garden that is Michoacán!

"I knew that Uruapanenses, like all Michoacanos, are not downcast by either bad governments or bad men. They struggle and work every day to make their city and their state a place where people can live and work in peace.
"Since childhood I have heard of the beauties of Michoacán. In the choir of Zaragoza, we sang the beautiful song that encourages birds to abandon their flight:
  • "If you are going to paradise, stopyou are flying over it right now."
  • Then later, referring to the lands of Michoacán: "Yes, you have what you hoped for." Wow!
"I saw Lake Zirahuén's calm waters...maintained by its inhabitants and neighbors.

"I brought home wonders coming from the hands of its artisans. 
"I enjoyed your culinary triumphs: ah, those uchepos [small tamales made with baby corn] are the flavor of 'glory', and those delicacies of the Casa de Blanca, where the rich cuisine of Michoacán rests among the beauty of landscape and tradition! 
"I went to the enchanted place where the Cupatítzio River begins—to see the water emerge from the ground is like watching the birth of God.
Water emerges from underground springs all along the trail
that winds alongside the Cupatitzio River.
"I heard the legend of the Devil's Knee*, and I heard the singing of a mournful pirecua**, Purhépecha song.

"Furthermore, by happy chance I found a bookstore—I do not seek books; they find me—appropriately, it is named Paradise, and there I found very good books for just a few pesos. Again I say, paradise. That's Uruápan...and that's Michoacán. 
"Thank you, my cordial, most kind friends from Canacintra: Alfonso, Diana and Luis, Mario and Isabella, for this gift of life that your invitation gave to me and for your kind attentions, as I've already said. I hope with my soul—and also with my body—to return to Uruápan. Meanwhile, I'm already uruapanizado'd... ."

The thank-you letter brought back many delightful memories and associations, among them the Legend of the Devil's Knee, of which there are innumerable versions! Here's one that appealed to me: its simplicity inviting translation.
"Hundreds of years ago, Uruápan felt the happy life provided by the fertility of its soil. The Cupatitizo River murmured its eternal song in the shade of the trees that were beginning to feel the first fruits. The virgin lands were covered with a blanket of greenery dotted with flowers and huts built at the impulse of the first signs that Christianity was spreading among the people. The smoke rising from their homes into the sky mysteriously veiled the dense vegetation of the immense forest. 
"According to the legend, the day came when the Cupatitzio stopped murmuring as before, leaving the riverbed dry and drying out the stream's crystal waves. Without water or dew, the green fields abandoned their green for the sad yellow of dry leaves, and the trees in the orchards twisted their branches, dropping their fruit without color and without nectar, as tears of overwhelming despair. All was anguish, all grief, all prayers and tears.

"In the darkness of his cell, Fray Juan de San Miguel pondered the magnitude of the misfortune, knelt with his knees on the ground and directed his eyes to the sky in a supreme prayer of anguish. At one point, inspired by a divine ray that penetrated the church, he rang the church bells and made his voice call to the Purhépecha people. When they arrived and hurried to the Friar, they saw on his illuminated face the glimmer of heavenly hope.

"Soon after, the elders led a solemn procession of the image of the Virgin, surrounded by her court of honor. The solemn procession arrived at the source of the river, sad and dry as the eye without light. Fray Juan prayed for a few moments, then taking a little holy water, sprinkled it over the scorched rocks of the empty bed.

"Legend has it that the ground shook with a horrible tremor. An immense cry was heard that echoed over long distances and from the abyss emerged the figure of Satan who, upon meeting the Virgin replete with flowers and covered with aromatic incense, fell back frightened, crashing into a rock, which still has the hole left in it by his knee—the knee of the prince of darkness.

"Waters flowed again. The fields again turned green, the fruit ripened and joy was reborn. Since then, the Cupatitizio has never stopped murmuring its eternal song in the shade of dense coffee plantations, while in the branches the wind heralds the eternal symphony of nature."
Here's yet another version of the legend (in Spanish) accompanied by truly gorgeous photos of this enchanting spot. By the way, trout grown locally in farms are served at the restaurant at the top of the falls. Not to be missed!

**Pirekua [pronounced Peer-EH-coo-a] are traditional Purhépecha songs. Here's my translation of an unusually insightful description:
"A traditional song of the Purhépecha communities of the state of Michoacán, pirekua is performed by both men and women. The pirekua tradition draws on multiple cultural sources, including African, European and indigenous, which have combined to give rise to a wide diversity of styles. Regional variations have also been observed in thirty of today’s 165 Purhépecha communities. As a general rule, the pirekua has a slow rhythm, but the form also includes instrumental forms using other rhythms.
"The pirekua can be sung as a solo, duet or trio; it can also be accompanied by a chorus, string orchestras, or groups of string and wind instruments. Singers and interpreters of pirekua, called piréiechas, are known for their creativity and their interpretations of the ancient songs. The song texts are heavily symbolic and embrace a wide range of themes from historic events to religion, but they also touch not only on themes of love and courtship, but on social and political ideas as well. 
"The pirekua is an effective means of dialogue between families and the Purhépecha communities; in fact, it contributes to establishing and strengthening ties between families and the communities. By performing the songs in order to express feelings and communicate important events to the Purhépecha communities, the pirériechas fulfill a function of social mediation [like Europe's medieval troubadours].

"The pirekua is an oral tradition transmitted from generation to generation. Pirekua, however, is more than just a cultural expression maintained today; it is also a distinctive sign of identity and a medium of communication for more than 100,000 Purhépecha peoples."
UTube video: La pirekua, La Canta Tradicional de los P'urhépecha. The narration is in Spanish, but the message of the pirekua songs is perfectly clear; to top it all off, the scenes of Michoacán and Zirahuén are incredibly beautiful.
