Chocolate finds its way onto even the most simplistic dessert menus today to satisfy the sweetest sweet-tooth. In ancient Mesoamerica, chocolate was deemed a speciality food, achieving a sacred status.

The Maya and the Aztecs believed that cacao was discovered by the gods in a mountain and was to be given to the people following their creation. The Maya held a yearly festival to honor the cacao god Ek Chuah, which included several offerings and rituals to him. Although sustaining the high possibility that is was not a native Mesoamerican crop, the cacao tree was one of the ancient Maya and Aztec’s most prized.

The warm, liquid form of the chocolate consumed was very different from today’s hot cocoa, being laden with chili powder and other spices making it a hot and sultry treat popular with royalty while lay people occasionally enjoyed its healing qualities. The Spanish who moved into Mesoamerica were unfamiliar with the ‘savage’ flavors of the spicy chocolate and determined that it would not be popular as it stood and was not to sent back home without proper adjustments like the elimination of many spices and the addition of sweetening ingredients.

While archaeological evidence for cacao use by the Aztecs and Maya is rather limited, pictorial and iconographic evidence is quite substantial. The goal of this poster is to demonstrate the many ways in which the cacao tree was especially important ritually, medically and spiritually to the ancient civilizations of Mesoamerica..

For nearly 3500 years the world has indulged in chocolate; chocolate bars, candy kisses, hot cocoa, chocolate ice-cream and numerous other forms. The idea of a chocolate treat is far from a modern one. The use of chocolate began in the New World with the ancient Olmec civilization (1500 BC-500 BC) in Mesoamerican and continued on through the time of the Maya and Aztecs before making its trek across to the Old World in the 16th century.

The formulation and serving techniques of the chocolate were somewhat different than today. Mainly consumed as an unheated liquid by the Aztecs and generally heated by the Maya, chocolate was the drink of choice for the elites and with the addition of hot chilies, maize, spices, peanut butter, vanilla and other flavor and texture enhancers, made the chocolate beverage a spicy and sultry drink enjoyed only by those who are able to afford it or by those who are specifically chosen to enjoy its benefits. Over the years, cacao, its components and chocolate in one form or another, have been used in more ways that just for a pleasure drink. It is known to have healing and preventative properties and has been documented in both ancient and modern medical journals.

History of the Cacao Tree and its Cultivation:

The cacao (Theobroma cacao) tree is a member of Sterculiaceae family of evergreens. Today, we find the wild trees at various elevations (200-400m) in the Amazon Rainforest as well as the Orinco River basins. The tree produces fruits approximately the size and shape of an American football. Each pod contains an average of 40 seeds (commonly referred to as ‘beans’), which are what is used to make cocoa powder, cocoa butter and chocolate (Rissolo per. comm. 2005).

The cultivation of a cacao tree and its seeds is a rather involved and time-consuming process. In the wild, the trees can grow to a height of over 60 feet; however in a plantation setting it is typical to see them only at a maximum of 20 feet to ease the harvesting labour. The planted trees take four or five years to flower. Once pollinated, each flower begins to produce a pod with will grow to be about one pound in weight and contain about 40 seeds surrounded by a naturally sweet white pulp. The pods are unable to open on their own accord and must so be done with human (or animal) intervention.

The pods will ripen throughout the year and there are normally two main harvests. The pods are opened by hand and the pulp and are seeds extracted According to Coe and Coe (1996) the four steps needed to produce the cacao ‘nibs’ (shelled and de-germed beans) are: fermentation, drying, roasting and winnowing. These steps are still followed in today’s modern chocolate making cultures, regardless of the technologies available to them. The four stages are summarized below.

Fermentation is a confusing word choice as the cacao is not fermented into an alcohol, although it could be. As performed by the ancient people of Mesoamerica, the beans (seeds) are fermented for anywhere from three to six days, depending on the type of bean. During this time, chemical processes are occurring; the pulp liquefies, and drains away as the temperature increases and the seeds begin to germinate but are soon killed by the high temperature and acidity which is the desired effect as the chocolate will fail to taste like chocolate if this does not occur (Coe and Coe 1996, 24). Once fermentation is complete, the beans are dried on flat mats left out in the sun for one to two weeks. Roasting the beans for approximately 70-115 minutes at temperatures of around 215 degrees F is vital for the drawing out of the chocolate flavour.

The beans are roasted at a slightly higher temperature in order to produce cocoa powder. The final step is the removal of the outer shell of the bean (winnowing). Once winnowing has occurred, the beans can be ground into a paste, commonly known as ‘cacao liquor’, which is non-alcoholic (Coe and Coe 1996, 25). The process is time consuming and minimal chocolate is retrieved from each pod, but the value is so great and the time used in order to prepare the chocolate adds to the sacredness of the end product.

Cocoa Tree

Cacao butter is made up of the fat inside the nib. It is extracted during the drying process and the fat was and still is used not only as an addition to quality chocolate, but as an ingredient in many cosmetics and skin-care products. The word cacao most likely originated with the Olmecs who resided in the lowland region of Mexico on the eastern gulf coast (Dillinger et al. 2000 and Coe & Coe 1996). The tree obtained its modern name from the eighteenth century Swedish biologist, Carolus Linnaeus. While developing a system for classifying living organisms, he assigned the botanical name Theobroma cacao to the chocolate tree. Theobroma, in Latin, means “food of the gods,” while cacao refers to the native word for the plant (Coe and Coe 1996, 17).

In the most basic of terms, cacao is a culturally edible material which grows on trees in Central and South America. To the ancient lay people of Mesoamerica, it was so much more than a food item. Cacao seeds were actually so valued as to be used for currency, while the subsequent beverages were used as offerings to the gods and as the champagne-of-the-time. A 1545 Nahuatl (Mayan language) document provides a list of the prices of food items; a turkey hen is worth 100 cacao beans, a hare or forest rabbit or is worth 100 cacao beans, a large tomato is one bean and one turkey egg is worth three beans, among other food items (Coe and Coe 1996, 98-99).

There is doubt as to whether or not the cacao tree is native to Mesoamerica. Specific climatic conditions are required for the needy cacao tree to grow. Surprisingly, the trees have been reported to have grown and thrived in the northern part of the Yucatan Peninsula where the climate would normally be far too harsh. The area has a long, hot and dry season yielding a mere 50mm of rainfall a year. Cacao trees require year round humidity and plenty of rainfall (2000mm) into well-drained soil in order to grow and propagate (Gomez-Pompa et al. 1990, 247-249). Being a shade-loving species, the cacao is usually found growing under the canopy of taller, tropical trees and basking in the nutrient-rich soil made up of the abundant organic materials falling from the protective canopy-trees.

It is exceedingly difficult to recognize what the original properties of the wild populations of cacao trees prior to the Spanish contact were. South America has been considered to be the center of origin for cacao, but the question of when the transfer of the tree to Mesoamerica occurred still sparks controversy upon Mayanists as well as other archaeologists and historians (Gomez-Pompa et al. 1990, 249). However, there is absolutely no proof of South American usage of cacao prior to modern times and, according to Gomez-Pompa et al. (1990), it is unrealistic to assume that someone traveling from South America to Mexico could have (or would have) successfully brought the cacao seeds, while keeping them viable for the two-week trek, to be planted and cultivated in Mexico.

The seeds germinate quickly and will surely die if not kept moist and cool in the hot air that blankets the South American and Mesoamerican areas. It is therefore somewhat safe to assume that the trees do, in fact, grow naturally in the Mesoamerican area, but how? Unfortunately, at present, it unknown for certain whether or not these cacao groves occurred naturally or with human assistance. The answer may well lie in cenotes, (underground caves), or collapsed above-ground caves. These types of environments are similar to sinkholes and house a damp microenvironment virtually perfect for cacao growth. Groundwater in the cenotes is generally the food for the trees, which are by and large untouched by rainwater for half the year. Unfortunately, whether cacao trees naturally form and prosper or were originally brought into the area and planted in these sinkholes and cenotes, is still under investigation.

Iconographic and Archaeological Evidence:

Chocolate became popular as a drink among the Aztec upper classes, who could afford it. The custom was to serve chocolate after a feast, in a special cup (xicalli) made out of a calabash gourd. Royalty and upper elites ritualistically used elaborately painted pottery from which to drink the frothy concoction (Rissolo per. comm. 2005).

An impressive Mayan example of this is from a royal tomb in north-eastern Guatemala. It contained seven cylindrical containers, including a pot with a stirrup handle and screw-on lid. The notable piece was painted with hieroglyphs reading, “a drinking vessel for witik cacao, for kox cacao,” the still un-deciphered Mayan words which likely denote chocolate flavours (Coe and Coe 1996, 49 and Hall 1990). Laboratory analysis of its inner surface by came back positive for chocolate. All seven containers likely held varieties of the cacao beverage. There are thousands of these cylindrical vessels in collections, and the vast majority say right on them, ‘This is a vessel for chocolate,’ (Coe and Coe 1996).

Spouted vessels are a rare elite drinking vessel of the Preclassic Maya. Colha, in northern Belize, has yielded several of these types of drinking vessels. Dry-residue analysis using liquid-chromatography show chocolate use as early as 600BC. These vessels were only manufactured in the Preclassic period (900BC-AD250) (Hurst et al. 2002, 289).

Residue analyses on several vessels from ancient Maya burial sites indicate offerings of chocolate to the deceased (Dillinger 2000, Hurst et al. 1989 and Hall et al. 1990). In fact, a majority of the pottery assemblages from Maya sites of the Postclassic (prior to the Spanish conquest) era contained vessels used to hold chocolate for the dead to utilize during his/her afterlife. Analysis if the residues of four Maya tomb vessels at the site of Rio Azul in Guatemala have shown that the vessel once contained theobrommine and/or caffeine which are both contents of cacao (Hall et al. 1990, 139).

Hall and his researchers surveyed the literature provided by the laboratories of the Hershey Foods Corporation Technical Center and determined that cacao is the only Mesoamerican food source which contained both theobrommine and caffeine. Therefore it has been deemed safe to conclude that any vessel which tests positive for these ingredients likely contained cacao in one form or another. Another 15 vessels which had a sort of locking mechanism, deemed by Hall (1990) to be a ‘child-proofing’ system, seemed to have once contained foods and liquids on which the deceased would subsist in the afterworld. As Hall (1990) states, many of the vessels had obvious inner rings of residue, some of which were slightly slanted, as if the pot was not entirely flat on the bottom.

This indicates the presence of a liquid having been stored. The glyphic writing on the outside of the vessels clearly display the Maya word for cacao along with additional un-deciphered glyphs, possibly eluding to the recipe of the contents, the maker of, or other general information about the contents which were once housed in the vessel (Hall, 1990, 139).

As suggested by the residue analysis, as well as iconographic evidence, the elites began frothing the chocolate to create a thick, foamy head using a Spanish invention called a molinillo. Prior to Spanish contact, the method mostly used to froth the liquid was pouring from extended heights into another vessel on the floor (Coe and Coe 1996).

Archaeological evidence from Mesoamerica, points to chocolate use beginning with the ancient Olmecs and carrying on through the time of the Maya and Aztecs. Evidence is sparse but comes from various parts of Mesoamerica. Whole cacao beans were recovered from Uaxactun, Guatemala, while in Belize, wood from ancient cacao trees has been uncovered along with ceramic vessels which tested positive for chocolate residues (Rissolo per. comm. 2005).

An example of a piece of iconographic evidence of the importance of cacao is a jadeite plaque uncovered inside a cenote in the town of Chichen Itza. The carved jade shows a man holding onto the trunk of a cacao tree covered with protruding cacao pods. The carving also contains the phonetic glyph for the word cacao pronounced ka-ka-w(a), or kakaw (Gomez-Pompa et al. 1990). An incense burner from the Late Classic period (AD 600-900) depicting a god surrounded by many cacao pods was uncovered in the Rio Bec region of Campeche (Gomez-Pompa et al. 1990 and Rissolo per. comm. 2005).

The only surviving written evidence from the Classic era Maya, are the extravagantly decorated vessels which joined the elite in their tombs. There is little else known about the peasants who actually grew and cultivated the trees, or how the May ate or drank their chocolate (Coe and Coe 1996, 45-46).

Ritual Use:

The use of chocolate had many ritualistic, spiritual and political meanings for the ancient peoples of Mesoamerica. According to similar creation stories of both the Aztec and the Maya, the gods discovered the cacao in a mountain named the Mountain of Sustenance (named by the Maya), along with other delectable foods. The Maya version tells the story of the Plumed Serpent (a god), who gave the people, recently made from maize by the divine grandmother goddess, Xmucane, the cacao on which to feast (Dillinger et al. 2000). The gods also provided maize, fruits and other desired foods.

When it comes to ritual use of chocolate, usually, only the male, elite and royals consumed cacao in a liquid form (Rissolo per. comm 2005), making the sweet treat one of high status individuals. Perceived as being an intoxicating food, the chocolate drink was a forbidden food for both women and children in a ritual setting (Dillinger et al. 2000, 2057s).

Priests would often prepare chocolate as a drink for religious ceremonies or offer cacao seeds to the gods. The Maya held a yearly festival to honor the cacao god Ek Chuah, which included several offerings and rituals to him; chocolate beverages, blood, dancing and other gifts such as the sacrifice of cacao-colored dogs and feathers, incense and cacao seeds (Rissolo per. comm.. 2005). According to Aztec history, a similar yearly festival in the capital city of Tenochtitlan took place with the sacrifice of a warrior captured from an enemy group during battle.

For forty days he was dressed up in the colorful feathers and jewels of the god Quetzalcoatl and ordered to dance for the appeasement of the god of war and the sun; Huitzilopochtli, all the while being treated like a god, but being caged at night. If he appeared agitated or nervous due to his impending doom, the captive would be fed a relaxing drink. He consumed a thick reddish liquid which would enable him to put his fears of eminent death aside and continue to entertain the god. The drink was an intoxicating chocolate blend with the color of blood. His dancing and movements seemed to welcome the death to come, as if he was offering himself willingly. Soon after which, his heart was carved out of his body to be offered to the god that would ensure the rising of the morrows sun (Coe and Coe 1996, 102 and Rissolo per. comm. 2005).

The offering of blood also occasionally consisted of priests lancing their own earlobes or kings lancing their penises with obsidian blades drizzling their own blood to cover cacao and offering it to the gods whom they were honoring (Rissolo per. comm. 2005). There are many, strong ethnographic sources (Thompson 1956) which demonstrate the importance of these two liquids; blood and chocolate among the Aztecs and the late Post-Classic Maya. They were both considered sacred and were thus regularly offered during ritual practices.

Baptisms of newborn babies and marriages required the ritual use of chocolate as well. The pre-Spanish Maya baptismal ritual consisted of cacao seeds ground up with flowers and pure water was used to anoint the heads, feet, hands and faces of the children, whole chocolate mixed with corn gruel was offered in special clay pottery to be used during wedding ceremonies (Rissolo per comm. 2005).

There were several types of drinks prepared for different occasions as well. Depending on the person for whom the drink was prepared, different ingredients were added or not added. Given the abundance of different types of chilies in the region, the drink could have been anywhere from mild to scalding and given the grinding techniques of various other additives, the drink may be thick, lumpy, or watery. Many recipes for chocolate drinks have made their way around the world. For example, Sahagun’s (who will be discussed in the next section) native informants give him a ‘menu’ of chocolate drinks which are suitable to be served to the ruler (Coe and Coe 1996, 89). Also, medicinally, drinks were prepared to have desired effects on the human body, which leads us into the medicinal use of the cacao and chocolate.

Medicinal Use:

Not only was chocolate used for ritual purposes but it was avidly used for medicinal reasons as well. Healing and preventative medicines as well as a tool for administering foul-tasting medicines were the two primary medicinal uses for the chocolate. Ancient Aztec sources can trace the use of the chocolate as a medical tool. Sources include the Badianus Manuscript, the Princton Codex and the Florentine Codex.

The Florentine Codex (1590 AD) contained an enormous list of medical uses for chocolate. It was prepared by priest Bernardino de Sahagun from Spain who lived and worked in the ‘New Spain’ for 60 years, collecting vital medicinal information regarding the use of chocolate for the body both internally and externally (Dillinger et al. 2000). Chocolate lessens agitation (Quelus 1730, 51), reduces angina and asthma (Villanueva y Francesconi, 1890, 231 and Hughes 1672, 153-154), reduces cancer (Villanueva y Francesconi, 1890, 239) and has a calming affect (Brillat-Savarin 1825, 100). It reduces emaciation (Hernandez 1577, 305), improves energy (Stubbe 1662, 3), relieves hoarseness (Quelus 1730, 76), reduces fever (Hernandez 1577, 305) and quenches thirst (Quelus 1730, 46).

It is also known to clean the teeth (Dillinger et al 2000, 2061s); of course modern-day dentists may disagree. The increase in sexual appetite, fertility and abetted longevity were other benefits of the chocolate. It is stated that Montezuma, prior to visiting his grand harem, would consume up to 50 goblets of a hot chocolate drink to ensure a suitable visit to each member in the group (Aguilera 1985, 119 and Dillinger et al. 2000, 2062s). Another benefit is that of consuming cacao-tree bark. It assists in reducing abdominal pain (Morton, 1981, 556-557). Externally, cacao was helpful in soothing burns, bronchitis and in disinfecting cuts. One can facilitate childbirth by eating the fruit pulp of the cacao pod. Even the leaves of the cacao tree act as antiseptics for external wounds (Morton, 1981, 556-557). Aztec soldiers marching off to battle were often given chocolate beverages to fortify and sustain them during battle (chocolate.org, Rissolo per comm. 2008). There are nearly 300 medicinal uses on de Sahagun’s list for the versatile cacao tree; however, he also added a warning label of sorts;

“[Green cacao] makes one drunk, takes effect on one, makes one dizzy, confuses one, makes one sick, deranges one. When an ordinary amount is drunk, it gladdens one, refreshes one, consoles one, invigorates one. Thus it is said: ‘I take cacao. I wet my lips. I refresh myself’ (Sahagun 1590, 119-120)”.

The Spanish Influence:

The arrival of Christopher Columbus and his officers brought an ignorance of the importance of cacao to the new world. Upon his return to Spain, Columbus toted a mere handful of cacao seeds. Only after Hernan Cortes came upon the chocolate, did its popularity in the Old World increase (Coe and Coe 1996). The bitter, spicy taste of the drink did little to satisfy Columbus and his men. They were unaware of the importance of the drink and could not bear to even choke it down. Upon its arrival in Spain, it was re- flavored with cane sugar (previously unavailable in Mesoamerica), allspice and honey to a sweet, smooth beverage. Whilst in Spain, it too, was an elite-only drink but eventually ‘chocolate saloons’ began to open, making it available to all people (Rissolo per. comm. 2005).

The Spanish, who prepared the chocolate drink for their own pleasure, did so quite differently from the ancient Mesoamericans and without the knowledge of the rest of Europe. The addition of hot and spicy additives was not palatable to the Spanish consumer and therefore substituted them with sweet additions such as cane sugar, cinnamon, honey and other flavor enhancers. In his History of the New World (1575), Girolamo Benzoni negatively states: “It seemed more like a drink for pigs than a drink for humanity………But then, as there was a shortage of wine, so as not to be always drinking water, I did like the others. The taste is somewhat bitter, it satisfies and refreshes the body, but does not inebriate, and it is the best and most expensive merchandise, according to the Indians of that country (Benzoni 1575)”

The chocolate was reserved for the higher classes as well and the Spanish government went to great lengths to ensure only the wealthy could indulge. They increased taxes on cacao product greatly to ensure only the elite could afford its benefits. Spain and Portugal kept it hidden from the rest of the world and at first only used it for medicinal purposes but the allure soon caught on. The allure was in fact so high that arguments as to whether or not chocolate could be considered a food or a beverage arose. To some, it satisfied and nourished the body like a solid food and therefore it must not be consumed during times of fasting. Eventually, much of the population, including the popes, agreed that it was not a solid food and therefore did not break the fast. By the late 17th century, chocolate became available to most of Europe and accessible to the general populations. Its popularity only increased and chocolate manufacturing companies like Hershey’s, Fry’s and Cadbury’s began opening around the globe to satisfy the people’s need for chocolate.

Conclusion:

The love for chocolate has not dwindled since its discovery. It is still a favorite among many cultures, societies, elites, royals and everyday people. The technologies, flavors, additives and reasons for consuming it have changed to allow for an increase and ease in production. Once a sacred liquid from ancient Mesoamerica; chocolate has found its way onto the dinner tables of the entire world. One need only look at the heart-shaped box of chocolates received on Valentine’s Day or the chocolate Easter egg found during a yearly egg-hunt to understand its importance in society today.

An international team of researchers from the University of York, the Institute of Anthropology and History in Mexico, Washington State University and Simon Fraser University have been studying the earliest indication of domestic turkeys in ancient Mexico.
The team studied the spatial remains of 55 turkeys, dating from between 300BCE-1500CE in various parts of pre-Columbian Meso-America.
They discovered that Turkeys weren’t just a prized food source, but was also culturally significant for sacrifices and ritual practices.
Marie Skłodowska-Curie Fellow in the Department of Archaeology at the University of York, Dr Aurélie Manin, said:  “Turkey bones are rarely found in domestic refuse in Mesoamerica and most of the turkeys we studied had not been eaten – some were found buried in temples and human graves, perhaps as companions for the afterlife. This fits with what we know about the iconography of the period, where we see turkeys depicted as gods and appearing as symbols in the calendar.
“The archaeological evidence suggests that meat from deer and rabbit was a more popular meal choice for people in pre-Columbian societies; turkeys are likely to have also been kept for their increasingly important symbolic and cultural role”.
Dr Camilla Speller of the University of York said: “Even though humans in this part of the word had been practicing agriculture for around 10,000 years, the turkey was the first animal, other than the dog, people in Mesoamerica started to take under their control.
“Turkeys would have made a good choice for domestication as there were not many other animals of suitable temperament available and turkeys would have been drawn to human settlements searching for scraps”
Some of the remains the researchers analysed were from a cousin of the common turkey – the brightly plumed Ocellated turkey.  In a strange twist the researchers found that the diets of these more ornate birds remained largely composed of wild plants and insects, suggesting that they were left to roam free and never domesticated.
The team also measured the carbon isotope ratios in the turkey bones to reconstruct their diets. They found that the turkeys were gobbling crops cultivated by humans such as corn in increasing amounts, particularly in the centuries leading up to Spanish exploration, implying more intensive farming of the birds.
Interestingly, the gradual intensification of turkey farming does not directly correlate to an increase in human population size, a link you would expect to see if turkeys were reared simply as a source of nutrition.
By analysing the DNA of the birds, the researches were also able to confirm that modern European turkeys descend from Mexican ancestors.

These are preserved maize cobs from the El Gigante rockshelter, Honduras, directly dated by AMS 14C. The largest cob, pictured at middle, is roughly 10 cm (4 in) in length. The first four cobs from the left date to the Late Formative period (approximately 2,200 years BP), while the cob at the far right dates to the Late Archaic, nearly two millennia older (approximately 4,100 years BP). Research on specimens from El Gigante reveals that ancient farmers selected for numerous traits, developing and cultivating a wide array of maize

This is the El Gigante rockshelter in the western highlands of Honduras.

 

———————

Mid-summer corn on the cob is everywhere, but where did it all come from and how did it get to be the big, sweet, yellow ears we eat today? Some of the answers come from carbon dating ancient maize and other organic material from the El Gigante rock shelter in Honduras, according to a team of anthropologists who show that 4,300 years ago maize was sufficiently domesticated to serve as a staple crop in the Honduran highlands.

At its peak in the 14th century, Casas Grandes was home to as many as 3,000 people, likely serving as a trade center, trafficking goods and channelling cultural influences between what’s now central Mexico and the southwestern U.S.

The last meals of men and women buried centuries ago in the ancient city of Casas Grandes were dominated by corn, new research has found — from ground maize, to corn smut, to what archaeologists say is the first conclusive evidence of corn beer in the Greater Southwest.

And these clues were found in a long-overlooked source: the fossilized plaque on the teeth of the dead.

Archaeologists say these and other findings are providing important insights into the diet and lifeways of one of the most influential prehistoric cities in the region.

“The results of this study offer some of the first hard evidence for the production of corn beer, consumption of corn smut, and food processing methods,” said Daniel King, a graduate student in anthropology at Brigham Young University, who led the research.

“It is a step forward in understanding Casas Grandes human-plant interactions, especially diet.”

Casas Grandes, also known as Paquime, was a large settlement on the fringes of the Mogollon culture to the north and Mesoamerica to the south.

At its peak in the 14th century, the city was home to as many as 3,000 people, likely serving as a trade center, trafficking goods and channelling cultural influences between what’s now central Mexico and the southwestern U.S.

Situated in Chihuahua some 130 kilometers, or 80 miles, from the New Mexico border, Casas Grandes was excavated in the 1950s and ‘60s, revealing hundreds of human remains — some buried, some dismembered and placed in urns, others apparently left out in the open.

Now, a new project undertaken by Dr. Anne Katzenberg of the University of Calgary is revisiting those remains, in an effort to learn more about the people who lived and worked in the prehistoric city.

And King and his colleagues sought to do their part, by analyzing the teeth of the dead.

Specifically, they studied the tooth calculus of more than a hundred sets of human remains.

“Calculus is fossilized tooth tartar,” King said.

“If teeth aren’t cleaned regularly, then the tartar, which can trap pretty much anything in it, such as algae, plants, fungus, or fibers, will slowly mineralize with everything stuck in it and turn into calculus, while the microremains turn into microfossils.”

To get at this microscopic evidence, the team recovered tartar from the remains of 110 people found within the ancient city and from other sites in the Casas Grandes River valley, all buried between 700 and 1450 CE.

Of those 110 samples, 63 yielded some sort of microscopic remains.

The most common traces the researchers found were starch granules, mostly bits of corn, which accounted for 36 percent of the samples.

Also common were phytoliths — tiny mineral fragments — that came from grasses and squash.

And more than 10 percent of the samples revealed the presence of corn smut — an edible, nutritious fungus that grows on corn and is still considered a delicacy, known today by its Aztec name, huitlacoche.

But while corn appears often in the dental record of Casas Grandes’ dead, that’s not necessarily a reflection of the population’s diet as a whole, King noted.

“Given the nature of calculus, any microremains recovered are going to be from the last days or weeks of the person’s life, maybe a month or two, but not longer,” he explained.

“So reconstructing diet, in the long term sense, doesn’t work with calculus.

“However,” he added, “identifying specific foodstuffs — like corn beer, fish, chile, et cetera — is useful, as many of them can’t be seen in the results of other studies.”

And in this regard, King said, the “most interesting results” of his team’s research was the discovery of corn alcohol.

Three of the samples revealed granules of maize that bore the unmistakable signs of fermentation, he said — including swelling and fragmentation caused by being heated at three distinct temperatures, and striations created by the fermenting process.

These bloated, broken grains seem to be the result of making chicha — a corn beer whose use has been recorded in Central and South America for as much as 5,000 years, King said.

In those cultures, brewing and consuming chicha is thought to have held ceremonial value, but it may have held other functions as well, he noted.

“We don’t have enough information to determine [chicha’s] use,” King said.

“Based on ethnographic accounts, we default to ‘ritual’, although I always think that’s a cop-out answer.

“We know modern groups used corn beer or similar drinks in religious ceremonies, so that’s all we can go off of.”

In addition, King noted, the burial contexts of the samples haven’t yet been analyzed, so archaeologists can’t yet draw conclusions about whether beer consumption was limited, for example, to a certain social class.

Moreover, he added, this is the first “substantial evidence” of corn beer in the Greater Southwest, so it’s possible that chicha may have served a different function in Casas Grandes than it did in Mesoamerica.

When it comes to beer in the southwestern archaeological record, he said, “almost nothing exists for northern Mexico or the American Southwest. The results we posted may be the first of their kind for this region.”

Some ceramic fragments found near Casas Grandes, for example, have displayed microscopic “pitting” that could have been caused by fermentation, he noted.

And a study in 2007 found traces consistent with fermentation in potsherds from Ancestral Puebloan settlements in New Mexico; but researchers cautioned that the fermentation may have been accidental, and the findings were described as “provocative but inconclusive.”

King’s new findings, then, raise the question of how the custom of brewing corn beer arrived at Casas Grandes, as well as when, and by whom.

“The best archaeological evidence we have for corn beer and other alcoholic drinks comes from Peru or Mesoamerica,” King said.

“So, if anything, the idea for corn fermentation came up from the south, but that is still conjecture at this point.”

As for when beer came to town, his findings do provide some insights.

His team studied teeth dating back as far as the year 700, but the fermented granules were only detected on remains dated to the so-called Medio Period of Casas Grandes — a cultural heyday that spanned from about 1200 CE to 1450 CE — suggesting that chicha might have been a relatively recent phenomenon.

“Our results show that maize was used throughout various time periods, but evidence for maize fermentation only comes from the Medio period,” he said.

“This is not to say such use did not exist in the [earlier] period, only that our results don’t currently support that idea.”

But whether it was brewed, chewed, or cooked, the corn of Casas Grandes may, in time, teach us volumes, not just about diet, but also about the social interactions that shaped one of the most important cultural crossroads in ancient North America.

“The continuity of maize use throughout the two time periods is important,” King said.

“It may suggest a continuity of people, thereby supporting an in situ development.

“Turning maize into beer during the Medio period, however, could suggest an influx of new ideas — or perhaps even people — during that time, which might indicate outside influence — either foreigners coming to Casas Grandes, or locals traveling and coming back with new ideas.”

jade corn cobe

A mysterious corn cob shaped artifact, dating to somewhere between 900 B.C. and 400 B.C., has been discovered underwater at the site of Arroyo Pesquero in Veracruz, Mexico. 

Made of jadeite, a material that is harder than steel, the artifact has designs on it that are difficult to put into words. It contains rectangular shapes, engraved lines and a cone that looks like it is emerging from the top. It looks like a corncob in an abstract way archaeologists say.

It’s an “extraordinary and unusual archaeological specimen made of mottled brown-and-white jadeite,” the team wrote in an article published recently in the journal Ancient Mesoamerica. 

Pesquero archaeological project, discovered the artifact in 2012 while diving with Jeffery Delsescaux about 2 to 3 meters (6.6 to 9.8 feet) below the surface of a deep stream.

“Underwater conditions were particularly challenging and included near-zero visibility and many obstructions, including large logs, smaller debris, partially decomposed leaves and other vegetation,” the team wrote.

The artifact dates to a time when a civilization now called the Olmec flourished in the area. The Olmec people built stone statues of giant human heads and constructed a city now called “La Venta” about 10 miles (16 kilometers) northeast of Arroyo Pesquero. The city, which may have supported some 10,000 people, contained a 112-foot-high (34 m) 

“The iconography is pretty difficult to interpret; it’s definitely not clear,” said Carl Wendt, a professor at California State University, Fullerton who is directing the project. “It seems to be an abstract representation, I believe, of a cob of corn,” he said. Corn, along with beans and squash, was an important part of the diet for people in ancient Mesoamerica.

The artifact may have had several uses. “While it certainly could have once been the handle of a bloodletter, in its current form, we argue that it probably would have been attached, as a finial, to a staff and functioned as a symbol of power and authority,” the team wrote in the article.

In the end, the artifact may have been placed in the stream as an offering, Wendt said. The offering could have been connected to deities, ancestor veneration or magic, he added. Over the past 50 years thousands of artifacts have been found at the site and they may have been left as offerings, archaeologists say.

A sacred place

The site where the artifacts were found is a place where freshwater intersects with saltwater, Wendt said, noting that jellyfish from the ocean can get into the stream during heavy rain. To the Olmec, this intersection of freshwater and saltwater may have had great importance.

“While having practical importance today as a spot to collect freshwater, in Olmec times, the confluence would also have been important for symbolic and cosmological reasons, and an ideal place for a ritual hoard or votive offerings,” the team wrote in the journal article.

So far, the archaeologists have found no buildings at Arroyo Pesquero that date to between 900 B.C. and 400 B.C. (when the offerings were made). Rather it is the water that is important the researchers said.

“Freshwater, so critical to daily life, was relatively scarce in a region of stagnant swamps,” the team wrote. “It is no wonder that springs and other freshwater sources were sacred places, and sacrificing [objects] at them was an important part of Olmec ritual.”

Wendt co-founded the Arroyo Pesquero archaeological project in 2005 so that the site could be studied scientifically. While thousands of artifacts have been found at the site over the past 50 years many lack details about their origins. Some of them were found by looters and are in private collections.

Topic: Ancient drinking cup

Excavating a remote Maya palace in the ruined city of Uxul, archaeologists in Mexico have uncovered the ancient tomb of a young prince—and a rare artifact.

cup of Mayan Prince

The floor of an entrance building within Uxul’s 11-building royal complex concealed the entrance to the small chamber, which held the remains of the 20- to 25-year-old man and nine ceramic objects.

On one cup, “there was a simple message … in elegantly modeled hieroglyphics that read: ‘[This is] the cup of the young man/prince,'” team member Nikolai Grube, an anthropologist at Germany’s University of Bonn, said in a late-July statement.

Another cup bears a date, which Grube and colleague Kai Delvendahl interpret to mean the year A.D. 711, giving some indication as to when the prince lived and died.

It’s common for Maya artifacts to refer to their owners, Grube said. But all previous princely drinking vessels have been excavated “illegally, without controlled excavation, by looters. This is the first time we have found such a vessel in an archaeological context.”

The Maya civilization sprawled across much of modern-day Guatemala, Belize, and Mexico’s Yucatán Peninsula. Around A.D. 900 the so-called Classic era of the Maya Empire came to a close after a series of droughts and perhaps political strife.

The Man Who Wouldn’t Be King

Despite its obvious archaeological attractions, the small tomb at Uxul (ooh-SHOOL) is noticeably lacking in jade jewelry—suggesting the prince was not in line for the throne, experts say.

If he had been, archaeologist Jennifer Mathews said, “you would see very lavish objects like jade masks made in the individual’s likeness, jade earspools, or other elaborate jade objects.

“We don’t see that in this particular case, so they think that this was a guy who was part of the royal family but who was not in line for the throne,” added Mathews, of Texas’s Trinity University, who wasn’t part of the project.
Dig member Grube ruled out the possibility that any jade might have been looted from the tomb. It was “clearly sealed” before the excavation, with a stone bench perched atop the entrance for good measure, he told National Geographic News.

Prestige and Power

Though the young Maya prince may have had no hope of inheriting the kingdom, his fortunes look to have been on the rise.

Until 705, Calakmul, a Maya metropolis about 16 miles (26 kilometers) away, had ruled Uxul in today’s Campeche state. After that time Calakmul’s influence receded, and the prince’s family became the local rulers of Uxul. (See a map of the Maya civilization.)

In Maya culture, rulers were seen as godlike, and “they would have been lavished with all kinds of goods,” Trinity University’s Mathews added.

“Overall, his family would have had more prestige and power. I guess inadvertently he would have received benefits from that.”
