On the afternoon of the Equinox the Feathered Serpent descends in a glory of shadow and light down the great pyramid, signaling the most auspicious time to plant the essential and most revered food staple of the Maya, corn. This event is the most dramatic display of Mayan astronomical knowledge encoded into architecture of any Mayan site yet discovered.
Tulum, Coba, Chichen Itza Equinox
The delegate of the National Institute of Anthropology and History (INAH), Eduardo López Calzada, announced that in Chichen Itza and Dzibilchaltún preparations continue for the observation of the phenomenon archaeo-astronomical of the spring equinox, to be held on Sunday March 20.
Although traditionally the start of the spring is related to the birth of Father of the Americas, Benito Pablo Juárez García, on March 21, he explores the possibility of extending the operations to two archaeological sites.
So far, it is contemplated that they will not exempt the payment of the visitors, the cost of entry is 49 pesos Dzibilchaltún, while for Chichen Itza, 51 pesos. The fee is for Cultur not the National Institute of Anthropology and History.
Currently “the details are keyed for both events,” because to Chichen Itza are expected to attend 50 thousand people, while for Dzibilchaltún, about five thousand.
Lopez Calzada mentioned that next week, INAH will announce in detail the operations to be implemented.
The astronomer Eddie Ariel Salazar Gamboa reported that on Sunday 20, at 17:21 pm will be the spring equinox “by definition”, because the planet is completely vertical.
The equinox is defined as the time of year the Earth’s axis is in a position to the sun, when the sun’s rays reach both the North and South Pole.
However, in the Yucatan Peninsula, the equality of the days will be on the 14th next Monday, as the sun appears over the horizon at 6:08 pm and lowers at 18:08, while the Tuesday, May 15 it will rise at 6:07 and will go down at 18:07. That is, the day and night will have duration of exactly 12 hours.
In the case of the phenomenon of Dzibilchaltún archaeo-astronomical, “Kin” the Mayan god of the sun, will enter from the East through the door, illuminating a dark room which is right in the middle of the building and out the west door. Even the windows are aligned and some halls, called by Victor Segovia Pinto as “calibrators.”
While in Chichen Itza, the effects will start at 15:00 hours, when the balustrade Kukulcan creeps northwest of El Castillo, to form a snake with seven triangles of light, which disappear as the sun moves towards the horizon.
