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.

In Maya Political Science: Time, Astronomy, and the Cosmos, Prudence M. Rice proposed a new model of Maya political organization in which geopolitical seats of power rotated according to a 256-year calendar cycle known as the May. This fundamental connection between timekeeping and Maya political organization sparked Rice's interest in the origins of the two major calendars used by the ancient lowland Maya, one 260 days long, and the other having 365 days. In Maya Calendar Origins, she presents a provocative new thesis about the origins and development of the calendrical system. Integrating data from anthropology, archaeology, art history, astronomy, ethnohistory, myth, and linguistics, Rice argues that the Maya calendars developed about a millennium earlier than commonly thought, around 1200 BC, as an outgrowth of observations of the natural phenomena that scheduled the movements of late Archaic hunter-gatherer-collectors throughout what became Mesoamerica. She asserts that an understanding of the cycles of weather and celestial movements became the basis of power for early rulers, who could thereby claim "control" over supernatural cosmic forces. Rice shows how time became materialized—transformed into status objects such as monuments that encoded calendrical or temporal concerns—as well as politicized, becoming the foundation for societal order, political legitimization, and wealth. Rice's research also sheds new light on the origins of the Popol Vuh, which, Rice believes, encodes the history of the development of the Mesoamerican calendars. She also explores the connections between the Maya and early Olmec and Izapan cultures in the Isthmian region, who shared with the Maya the cosmovision and ideology incorporated into the calendrical systems.

Mesoamerica is one of the few places to witness the independent invention of writing. Bringing together new research, papers discuss the writing systems of Teotihuacan, Mixteca Baja, the Epiclassic period and Aztec writing of the Postclassic. These writing systems represent more than a millennium of written records and literacy in Mesoamerica.

“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

This volume is designed to recognize the important role that epigraphy has come to play in Middle American scholarship and to document significant achievements in three areas: dynastic history, phonetic decipherment, and calendrics.

Archaeoastronomy and the Maya illustrates archaeoastronomical approaches to ancient Mayan cultural production. The book is contextualized through a history of archaeoastronomical investigations into Mayan sites, originating in the 19th century discovery of astronomical tables within hieroglyphic books. Early 20th century archaeological excavations revealed inscriptions carved into stone that also preserved astronomical records, along with architecture that was built to reflect astronomical orientations. These materials provided the basis of a growing professionalized archaeoastronomy, blossoming in the 1970s and expanding into recent years. The chapters here exemplify the advances made in the field during the early 21st century as well as the on-going diversity of approaches, presenting new perspectives and discoveries in ancient Mayan astronomy that result from recent studies of architectural alignments, codices, epigraphy, iconography, ethnography, and calendrics. More than just investigations of esoteric ancient sciences, studies of ancient Mayan astronomy have profoundly aided our understanding of Mayan worldviews. Concepts of time and space, meanings encoded in religious art, intentions underlying architectural alignments, and even methods of political legitimization are all illuminated through the study of Mayan astronomy.
