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.

Did you know that before Aristotle and Galileo there were the Mayans? The Mayans were an ancient civilization that once lived in Mexico. They were intelligent people who developed their own calendar and studied math as well as astronomy. Develop an appreciation for this ancient civilization by reading all about them.

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.

The only small, popular book on the important subject of ancient calendars. The study of heavenly cycles is common to most ancient cultures. The ancient Egyptians, Chinese, and Babylonians all tried to make sense of the year. But it fell to the later Mesoamerican Maya to create a series of calendars that could be cross referenced. In doing so, the Maya discovered many strange numerical harmonics. Their lunar calendar was extremely accurate-far more so than the Greek Metonic cycle; they tracked Venus to an accuracy of less than a day in five hundred years and their tables could have been used to predict eclipses seven hundred years in the future. This book will provide a much needed compact guide to the Mayan calendar systems as well as covering the essentials of calendar development throughout the world.

Mayan daykeeper Hunbatz Men reveals the multi-calendar system of the Maya that guided the lives of his ancestors and how it can guide us today • The first book to reveal the secrets of the Mayan Pleiades calendar: the Tzek’eb • Explains how the Maya used their astronomical knowledge to guide their lives on Earth The Mayan Calendar has taken on special prominence with the imminent arrival of 2012, a date that many claim is the end of that calendar. However, as Mayan elder and daykeeper Hunbatz Men shows, the cosmological understanding of his ancestors was so sophisticated that they had not one, but many calendars, each based on the cycles of different systems in the cosmos. In this book he reveals for the first time the Tzek’eb, or Pleiades, Calendar of 26,000 years, which charts the revolution of our solar system around Alcyone, the central star of the Pleiades system. He also discusses the K’uuk’ulcan Calendar of the 4 seasons of the solar year and the wheel of the K’altunes Calendar, which is composed of 13 cycles of 20 years each that form a calendar of 260 years. In traditional Mayan culture the computation of time was not determined by simple economic or social motives. The calendars served the higher purpose of synchronizing the lives of human beings and their societies to the great cosmic pulsation, to the rhythm of the annual seasons, and to the other cycles that dictate changes upon Earth. Mayan understanding of the cosmic cycles was so exact that this knowledge could be used to influence all stages of life--from planning when to conceive (parents could choose not only the sex of their child but its vocation and future destiny) to plotting out the course of the entire society. Pyramids played a crucial role in applying this wisdom because, as Hunbatz Men shows, they were able to produce and transform energy in accordance with the cosmic cycles charted by the calendars. This book reveals for the first time the wisdom of the multi-calendar Mayan system and how it can help guide our modern world.
