From the Archives: An Islamic Map for a Christian King

When we last left Sicily,  the Roman Republic had taken Siracusa, which became the capital of Roman government in Sicily. The Romans held Sicily for 300 some years. The island was subsequently occupied by the Byzantine empire in 535 CE, Arabs from North Africa in 965 and the Normans in 1060. *

Under the Normans, Sicily enjoyed a brief period of Christian-Muslim synergy similar to that occurring in Spain at the same time. Here is one of my favorite stories from that period, which first ran in 2013.

 

Most maps made in twelfth century Europe were based on tradition and myth rather than scientific information. The only practical maps were mariners’ charts that showed coastlines, ports of call, shallows and places to take on provisions and water. Roger II, the Christian king of Sicily, wanted a map of the known world that was a factual as a mariner’s chart. In 1138, he hired well-known Muslim scholar al-Sharif al-Idrisi to collect and evaluate all available geographic knowledge and organize it into an accurate picture of the world.

For 15 years, al-Idrisi and a group of scholars studied and compared the work of previous geographers. They interviewed the crews of ships who docked at Sicily’s busy ports. They sent scientific expeditions, including draftsmen and cartographers, to collect information about relatively unknown places.

Finally, al-Idrisi was ready to make his map. He began by making a working copy on a drawing board, using compasses to accurately site individual places. The final copy was engraved on a great silver disk that was almost eighty inches in diameter and weighed over 300 pounds. Al-Idrisi explained that the disk was just a symbol for the shape of the world: “the earth is round like a sphere, and the waters adhere to it and are maintained on it through natural equilibrium which suffers no variation”

Al-Idrisi’s map was accompanied by a descriptive geography that contained all the information his college of geographers had collected. Its formal name was Nuzhat al-Mushtaq fi Ikhtiraq al-Afaq, or The Delight of One Who Wishes to Traverse the Regions of the World. It was more commonly known as Roger’s Book.

In 1160, the Sicilian barons revolted against Roger’s son, William. They looted the palace and burned the library, including Roger’s Book. Not surprisingly, the silver map disappeared. Al-Idrisi fled to North Africa with the Arabic text of Roger’s Book. His work survived in the Islamic world, but it was not available in Europe again until the Arabic text was printed in Rome in 1592.

In which I take a side trip in time and space to consider the Mayans, the Aztecs and Chocolate

During our visit to Antica Dolceria Bonajuta,  the artisanal chocolate producer in Modica, our guide emphasized the fact that most modern chocolatiers, who use heat based methods such as conching and tempering to create smooth chocolate with a shiny appearance. By contrast, the Bonajuta chocolate makers still used a traditional “cold-processing” method similar to that used in Mesoamerica. in which cacao beans were roasted on a metate ( a rock grinding stone) that was heated over charcoal and then pounded into a paste.

Cacao beans, and the cold-processing method arrived in Modica during the period of Spanish rule, which began soon after Spaniards invaded the Aztec empire and discovered chocolate, not only the cacao bean itself, but the highly flavored beverage served in the court of the Aztec emperors.

The cacao tree is native to Central America. It only grows in tropical areas with a temperature above 60 degrees Fahrenheit and year round moisture.  In its raw state the cacao bean grows in pods on the trees known botanically as “theobroma cacao,”from the Greek word for “food of the gods” and the Mayan word for the bean itself.

The Mayans* domesticated the cacao tree and grew it both in home gardens and in large commercial plantations.  They venerated the beans as a gift of the gods, using them in religious ceremonies and for healing.  Pots full of chocolate drink were included in the burial goods of important people. They also traded the beans throughout Central and South America as a valuable commodity. In fact, they had a god named Ykchaua who was the patron of cacao merchants.  They roasted the beans and used them to make spicy, bittersweet drinks, gruels, and porridges that they flavored in a variety of ways.

By the time of the Aztec empire,** the cacao plant was so highly valued that the beans were used as currency. One hundred cacao beans was one day’s wages for a porter.  The same amount could buy a slave or a hare.  Three beans would buy an egg or an avocado.  One bean would buy a tomato..  The beans were valuable enough that people would make counterfeit beans or mix them with less valuable material.

One reason the beans were so valuable is that the Aztecs could not grow the tropical cacao tree in the temperate highlands near their capital.  Cacao beans became the object of both trade and war. When the Aztecs conquered tropical lowland areas of the Gulf Coast from Vera Cruz to the Yucatan, tribute was often paid in cacao beans. In the reign of Ahuitzotl (1486-1502), the Aztecs conquered the province of Xoconochco specifically because it was famous for the production of high quality cacao.  One of the most important areas of cacao production, the Chontalpa of Tabasco, never became part of the Aztec empire.  The only way the Aztecs could get cacao beans grown in the huge Chontalpan cacao plantations was by traveling to the Chontalpan trading city of Xicallanco, which drew long distance traders from all over Mesoamerica.

The importance of cacao and other luxury products in Aztec society can be measured by the status of the long distance traders, called pochtecas.  Aztec society was very stratified and the pochtecas enjoyed a high rank.  There were twelve pochteca guilds in the empire, each with its own headquarters and warehouses.  Membership was hereditary.  The pochtecas were described and treated as warriors because their work was so dangerous.  They often traveled through hostile territory to reach the markets where they purchased luxury goods for the royal house and the nobility.  In addition to cacao, they traded for beautiful feathers, jaguar skins and amber.

In addition to rules about who could be a long distance trader, Aztec society had heavy restrictions on who could use or consume the luxury products that the pochteca brought back.  One of the luxury goods governed by these sumptuary laws was “xocolatl” (pronounced “shoco-latle”) or “bitter water”, a cold beverage made from cacao beans that had been ground into a paste and flavored with chilies, herbs, or honey. (The Mayans, by contrast, preferred their cacao hot.) Only the royal family, nobility, warriors and long distance traders were allowed to drink it.  A Spanish chronicler named Bernal Diaz del Castillo recorded that more than 2000 containers of chocolate with foam were drunk every day by Montezuma’s guard alone.   The other high ranking people in Aztec society, the priests, are not included in the lists of chocolate drinkers, possibly because the priesthood were expected to live in strict austerity.

The only commoners who ever had a chance to taste chocolate were soldiers on the march.  Ground cacao made into wafers was issued to every soldier on campaign as part of the military rations, along with toasted maize, maize flour, toasted tortillas, ground beans and bunches of dried chilies.

The sixteenth century Franciscan missionary, Fray Bernardino de Sahagún, listed nine different chocolate drinks served to the emperor in his twelve volume book on the Aztecs, A General History of New Spain.  They included “green cacao-pods, honeyed chocolate, flowered chocolate, flavored with green vanilla, bright red chocolate, huitztecolli-flower chocolate, flower-colored chocolate, black chocolate, white chocolate”.    In addition to vanilla, honey and cinnamon, the drinks were flavored with spices such as hot chilies, anise, achiote, and allspice.  It was poured from container to container to produce stiff foam that was an important element of the drink.  It was served at the end of a meal, like a dessert.

The Spaniards brought back cacao beans alongside other treasures, but the bitter beverage was slow to catch on in Europe until the Spanish added sugar—which arrived in Europe from Southeast Asia at much the same time.***  Once it was sweet, chocolate became a popular luxury item in Europe.

*Just to give you a sense of the timeline, because even chocolate needs context: The classic Mayan civilization flourished from around 250 to 900 CE. In the ninth century, the Mayan culture suffered from a major political collapse, in which cities were abandoned. A reduced version of the culture, marked by independent provinces that shared a common culture, survived to the eve of the Spanish conquest. The final independent Mayan city fell to the Spanish in 1697.

**The Mexica, as the Aztecs called themselves, are believed to have been a nomadic people who migrated into central Mexico in the thirteenth century and founded the city-state of Tenochtitlan in 1325 CE. In 1428, the Mexica allied with two other city-states, forming the Aztec Triple Alliance and the beginnings of what we know as the Aztec Empire. The Spanish, led by Hernando Cortez, arrived in 1519. Two years later, after a bitter siege, the Aztecs surrendered and Cortez began to build a new city on the ruins of Tenochtitlan.

Cheese, Chocolate, and Siracusa

Our second stop in Sicily was the city of Siracusa, which is a history nerd’s delight, or more accurately would have been a history nerd’s delight if we had been on a different kind of tour. (Two areas of the city are UNESCO World Heritage sites.)  Instead of spending our time at the city’s archeological park and museum, we visited a small producer of farmstead cheeses near Calascibetta one day and an artisanal chocolate producer that has been in business in Modica since 1880 the following day.*

Nonetheless we managed to get peek at the city’s rich history as we went past. As in Sicily as a whole, a series of foreign conquerors took the city over the centuries and left their mark without totally obliterating the cultures that came before. It is clear, even from the passing glance we managed, that Siracusa’s moment of historical glory was during the classical period, when it was one of the most important cities of the Hellenic world. Here are the bits that stuck with me:

  • Siracusa was founded in the eighth century BCE by settlers from the Greek city-state of Corinth and became a city-state in its own right. By the fifth century BCE, it rivaled Athens in size.
  • It was the birthplace of the mathematician and engineer Archimedes (c 287-212 BCE), who derived an approximation of pi, was one of the first to apply mathematics to physical phenomenon, articulated the law of buoyancy (known as Archimedes principle), and invented several machines, including an innovative screw pump.** He also designed a number of weapons that were used to defend the city when it was besieged by Romans. A Roman soldier killed Archimedes during the siege despite orders by the Roman proconsul Marcus Claudius Marcellus that he not be harmed, because obviously such an inventive scientist would be an asset to the Roman Republic.
  • The Romans successfully took the city in 212 BCE. Siracusa became the capital of the Roman government in Sicily and remained the most important city in Sicily until Palermo became the capital of the Norman kingdom of Sicily in 1130.
  • As was so often the case, conquerors used their predecessors monuments as quarries for building materials. The most notable example of this in Siracusa is the cathedral, which was built in the seventh century, when Siracusa was under Byzantine rule. Stone pillars from a fifth century BCE temple to Athena are integrated into the walls and shape the floor plan. Its facade was rebuilt in the baroque style after an earthquake in 1693 damaged the city.***

*No complaints here. We learned a lot about how both products were made and enjoyed meals centered onthem. Saffron cheese! Ricotta made that morning! An amazing cold chocolate drink!  I must admit, after a four course lunch that included chocolate in every course I was not interested in eating chocolate again for several days.

**Spoiler alert, the Archimedean screw will appear in a blog post coming to this site.

***You’ll be hearing more about that earthquake as well.
