Cosmology, Calendars, and Horizon-Based Astronomy in Ancient Mesoamerica is an interdisciplinary tour de force that establishes the critical role astronomy played in the religious and civic lives of the ancient peoples of Mesoamerica. Providing extraordinary examples of how Precolumbian peoples merged ideas about the cosmos with those concerning calendar and astronomy, the volume showcases the value of detailed examinations of astronomical data for understanding ancient cultures. The volume is divided into three sections: investigations into Mesoamerican horizon-based astronomy, the cosmological principles expressed in Mesoamerican religious imagery and rituals related to astronomy, and the aspects of Mesoamerican calendars related to archaeoastronomy. It also provides cutting-edge research on diverse topics such as records of calendar and horizon-based astronomical observation (like the Dresden and Borgia codices), iconography of burial assemblages, architectural alignment studies, urban planning, and counting or measuring devices. Contributors—who are among the most respected in their fields— explore new dimensions in Mesoamerican timekeeping and skywatching in the Olmec, Maya, Teotihuacano, Zapotec, and Aztec cultures. It will be of great interest to students and scholars of anthropology, archaeology, art history, and astronomy.

Many ancient civilizations have influenced and inspired people in the 21st century, and the Greeks and Romans continue to fascinate the West today, but of all the world's civilizations, none have intrigued people more than the Mayans, whose culture, astronomy, language, and mysterious disappearance all continue to captivate people. In the past decade especially, there has been a renewed focus on the Mayans, whose advanced calendar led many to speculate the world would end on the same date the Mayan calendar ended in 2012. For the Maya, astronomy was not a purely scientific pursuit but intimately linked to religious, mythological, and ideological elements that were of the highest importance. The celestial realm held a sacred nature, as did the many gods and goddesses that dwelt there, so for all Mesoamerican cultures, astronomy was a fundamental part of their everyday lives. Thus, astronomy was present in their calendars, religion, and even agriculture, and in close relation to astronomy, the concept of time was also an essential part of their worldview. The Maya recorded time on almost every surface they could, including lintels, cornices, panels, stelae, friezes, ceramics, and paper. This insistence on capturing dates has led many scholars to suggest the Maya were obsessed with time. The Maya had some of the most advanced astronomical measurements in the world, and their work built upon thousands of years, spanning from around 2500 BCE until the the arrival of the Spanish in 1519. Unlike the Maya, the Aztecs are not widely viewed or remembered with nuance, in part because their own leader burned extant Aztec writings and rewrote a mythologized history explaining his empire's dominance less than a century before the Spanish arrived. Naturally, Cortes and other Spaniards depicted the Aztecs as savages greatly in need of conversion to Catholicism. While the Maya are remembered for their astronomy, numeral system, and calendar, the Aztecs have primarily been remembered in a far narrower way, despite continuing to be a source of pride to Mexicans through the centuries. The Aztec recorded many of the astronomical events they observed in codices and hieroglyphic inscriptions, but the main evidence of their deep astronomical knowledge comes from their calendar system. This information was then used to plan the orientation of buildings and ceremonial centers, which were aligned to sunrises or sunsets corresponding to special dates, such as solstices or equinoxes. Observational calendars were also used to schedule agricultural activities, as well as rituals, festivals, and celebrations. Though the Spanish physically conquered them in quick fashion, the culture and legacy of the Inca Empire has continued to endure throughout the centuries in both Europe and South America, due in no small part to the fact they were one of the most advanced and sophisticated cultures on the continent. Like the Aztecs, the Spanish burned much of the Inca's extant writings, but it is estimated that as many as 35 million once fell under their banner, and the empire's administrative skills were so sharp that they kept accurate census records. Their religion, organization, and laws were also effectively centralized and tied to the rulers of the empire, and their military mobilization would have made the ancient Spartans proud. The sun was the main element present in the Inca worldview, so Inti, the sun god, was worshipped above all others and, even though the different parts of the empire were allowed to practice their individual beliefs, they were encouraged to venerate the sun. The connection with the sun even extended to their kings since they were considered to be the sons of the sun. Naturally, this meant astronomy was a key component of the Incas' beliefs, and in addition to the sun, the Inca observed the moon, stars, constellations, and some planets, all of which became integral parts of their cosmology.

This book contextualizes the discovery of a Venus astronomical pattern by a female Mayan astronomer at Chich'en Itza and the discovery's later adaptation and application at Mayapan. Calculating Brilliance brings different intellectual threads together across time and space, from the Classic to the Postclassic, the colonial period to the twenty-first century to offer a new vision for understanding Mayan astronomy.

“A prodigious work of unmatched interdisciplinary scholarship” on Maya astronomy and religion (Journal of Interdisciplinary History). Observations of the sun, moon, planets, and stars played a central role in ancient Maya lifeways, as they do today among contemporary Maya who maintain the traditional ways. This pathfinding book reconstructs ancient Maya astronomy and cosmology through the astronomical information encoded in Pre-Columbian Maya art and confirmed by the current practices of living Maya peoples. Susan Milbrath opens the book with a discussion of modern Maya beliefs about astronomy, along with essential information on naked-eye observation. She devotes subsequent chapters to Pre-Columbian astronomical imagery, which she traces back through time, starting from the Colonial and Postclassic eras. She delves into many aspects of the Maya astronomical images, including the major astronomical gods and their associated glyphs, astronomical almanacs in the Maya codices and changes in the imagery of the heavens over time. This investigation yields new data and a new synthesis of information about the specific astronomical events and cycles recorded in Maya art and architecture. Indeed, it constitutes the first major study of the relationship between art and astronomy in ancient Maya culture. “Milbrath has given us a comprehensive reference work that facilitates access to a very broad and varied body of literature spanning several disciplines.” ―Isis “Destined to become a standard reference work on Maya archeoastronomy . . . Utterly comprehensive.” —Andrea Stone, Professor of Art History, University of Wisconsin, Milwaukee

The Olmec language and Teotihuacan language are still outside this preliminary classification: the ones represented by the Olmec area and those of Teotihuacan, which are currently being studied and discovered. Though it is still difficult to prove, there is some probability that the Olmec language preceded Totonac. In contrast, it is more specific than the writings and speech of Teotihuacan, which led to Nahua's development. The Mexican population that migrated to Nicaragua later spread this language in its various variants throughout the central Valley of Mexico, even reaching the south of Mesoamerica, to Nicaragua. During the destruction and abandonment of Teotihuacan around 600, the written system of their successors, the Toltecs, was lost but may have been revived later in Aztec ideographic writing.

Astronomy Across Cultures: A History of Non-Western Astronomy consists of essays dealing with the astronomical knowledge and beliefs of cultures outside the United States and Europe. In addition to articles surveying Islamic, Chinese, Native American, Aboriginal Australian, Polynesian, Egyptian and Tibetan astronomy, among others, the book includes essays on Sky Tales and Why We Tell Them and Astronomy and Prehistory, and Astronomy and Astrology. The essays address the connections between science and culture and relate astronomical practices to the cultures which produced them. Each essay is well illustrated and contains an extensive bibliography. Because the geographic range is global, the book fills a gap in both the history of science and in cultural studies. It should find a place on the bookshelves of advanced undergraduate students, graduate students, and scholars, as well as in libraries serving those groups.
