Astronomers of the Maya discovered the principles of the movement of the planets across the sky long before the creation of the heliocentric model of Copernicus.
The artifact called the Dresden Codex is a copy created in the 11th century manuscript of the Maya written in the 8th century ad. This manuscript was the key to decoding the literature of this enigmatic civilization of the ancient Indians.
The Dresden Codex consists of 74 pages and contains the religious, scientific information, information on ceremonies, celebrations, as well as mathematical and astronomical calculations, prediction of eclipses and the nature of the movement of the moon across the sky.
Gherardo Aldana from the University of California, Santa Barbara (USA) studied one of the most obscure parts of the code – the Venus signs, which contain calculations of the motion of Venus across the sky, and 584-day calendar, compiled on the basis of these calculations.
Aldana long studied the table and found out that they are talking not just about the position of Venus in a specific period of time, and on real astronomical discovery of the long-term calculation of the position of Venus in the sky taking into account the errors that occur hundreds and thousands of years.
The Mayans knew that Venus takes across the sky and returns to the point where she was during the beginning of the observations not for 584 days, and for 583.92. Using this figure, the Indian astronomers calculated correction values and created a formula which should be applied to the values from Code to calculate the position of Venus.
A similar system of settlement, the Indians could come up with if I didn’t understand the fact that Venus, the Earth and other planets revolve around the Sun and not the Sun revolves around them. Indian Observatory was located in Chichen Itza (Caracol structure).
Civilization of the Maya reached the level of the founders of the European astronomy, such as Copernicus a few centuries before them.
