The Maya calendar is a system of calendars used in pre-Columbian Mesoamerica and in many modern communities in the Guatemalan highlands, Veracruz, Oaxaca and Chiapas, Mexico. The essentials of the Maya calendar are based upon a system which had been in common use throughout the region, dating back to at least the 5th century BC. It shares many aspects with calendars employed by other earlier Mesoamerican civilizations, such as the Zapotec and Olmec and contemporary or later ones such as the Mixtec and Aztec calendars. By the Maya mythological tradition, as documented in Colonial Yucatec accounts and reconstructed from Late Classic and Postclassic inscriptions, the deity Itzamna is frequentl…

The Zapotec civilization (Be'ena'a (Zapotec) "The People that came from the clouds"; c. 700 BC – AD 1521) is an indigenous pre-Columbian civilization that flourished in the Valley of Oaxaca in Mesoamerica. Archaeological evidence shows that their culture originated at least 2,500 years ago. The Zapotec archaeological site at the ancient city of Monte Albán has monumental buildings, ball courts, tombs and grave goods, including finely worked gold jewelry. Monte Albán was one of the first major cities in Mesoamerica. It was the center of a Zapotec state that dominated much of the territory which today is known as the Mexican state of Oaxaca. The Zapotec peoples are their modern descendants.

Mesoamerica is a historical region and cultural area comprising the modern-day lands of central and southern Mexico, all of Belize, Guatemala, El Salvador, western Honduras, and the Greater Nicoya region of Nicaragua and Costa Rica. As a cultural area, Mesoamerica is defined by a mosaic of cultural traits developed and shared by its indigenous cultures. In the pre-Columbian era, indigenous societies flourished in Mesoamerica for more than 3,000 years before the Spanish colonization of the Americas began on Hispaniola in 1493. In world history, Mesoamerica was the site of two historical transformations: (i) primary urban generation, and (ii) the formation of New World cultures from the mixtu…

The calendrical systems devised and used by the pre-Columbian cultures of Mesoamerica, primarily a 260-day year, were used in religious observances and social rituals, such as divination. The importance of aboriginal calendars in ritual and other aspects of Mesoamerican life was noted by many missionary priests, travelers, and colonial administrators, and later by ethnographers who described and recorded the cultures of contemporary Mesoamerican ethnic groups. These calendars have been dated to early as ca. 1100 BCE. By 500 BCE at the latest, the essentials were fully defined and functional. 260-day calendars are still used in the Guatemalan highlands, Veracruz, Oaxaca and Chiapas, Mexico.…

Science in the ancient world encompasses the earliest history of science from the protoscience of prehistory and ancient history to late antiquity. In ancient times, culture and knowledge were passed through oral tradition. The development of writing further enabled the preservation of knowledge and culture, allowing information to spread accurately. The earliest scientific traditions of the ancient world developed in the Ancient Near East, with Ancient Egypt and Babylonia in Mesopotamia. Later traditions of science during classical antiquity were advanced in ancient Persia, Greece, Rome, India, China, and Mesoamerica. Aside from alchemy and astrology that waned in importance during the Age…

Colonial Zapotec Calendars and Calendrical Astronomy

Evidence: — • authority: 72

In the history of the Americas, pre-Columbian era, also known as pre-contact era, pre-Hispanic or as pre-Cabraline era (the latter specifically framed in Brazil), spans from the initial peopling of the Americas in the Upper Paleolithic to the onset of European colonization, which began with Christopher Columbus's voyage in 1492. This era encompasses the history of Indigenous cultures prior to significant European influence, which in some cases did not occur until decades or even centuries after Columbus's arrival. During the pre-Columbian era, many civilizations developed permanent settlements, cities, agricultural practices, civic and monumental architecture, major earthworks, and complex…

The tzolkʼin (Mayan pronunciation: [t͡sol ˈkʼin], formerly and commonly tzolkin) is the 260-day Mesoamerican calendar used by the Maya civilization of pre-Columbian Mesoamerica. The tzolkʼin, the basic cycle of the Maya calendar, is a preeminent component in the society and rituals of the ancient and the modern Maya. The tzolkʼin is still used by several Maya communities in the Guatemalan highlands. While its use has been spreading in this region, this practice is opposed by Evangelical Christian converts in some Maya communities. The word tzolkʼin, meaning "division of days", is a western coinage in Yucatec Maya. Contemporary Maya groups who have maintained an unbroken count for over 500 y…

The Andean civilizations were South American complex societies of many indigenous people. They stretched down the spine of the Andes for 4,000 km (2,500 miles) from southern Colombia, to Ecuador and Peru, including the deserts of coastal Peru, to north Chile and northwest Argentina. Archaeologists believe that Andean civilizations first developed on the narrow coastal plain of the Pacific Ocean. The Caral or Norte Chico civilization of coastal Peru is the oldest known civilization in the Americas, dating back to 3500 BCE. Andean civilizations are one of at least five civilizations in the world deemed by scholars to be "pristine." The concept of a "pristine" civilization refers to a civiliza…

The history of mathematics deals with the origin of discoveries in mathematics and the mathematical methods and notation of the past. Before the modern age and worldwide spread of knowledge, written examples of new mathematical developments have come to light only in a few locales. From 3000 BC the Mesopotamian states of Sumer, Akkad and Assyria, followed closely by Ancient Egypt and the Levantine state of Ebla began using arithmetic, algebra and geometry for taxation, commerce, trade, and in astronomy, to record time and formulate calendars. The earliest mathematical texts available are from Mesopotamia and Egypt – Plimpton 322 (Babylonian c. 2000 – 1900 BC), the Rhind Mathematical Papyrus…

Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry to explain their origin and their overall evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, meteoroids, asteroids, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is the branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded histor…
