The ancient Mayan capital of Chichen Itza casts its spell whenever you visit it but o

n the day of the fall Equinox, the Pyramid of Kukulcan in the Great Plaza becomes a stairway to heaven and an ancient god returns to earth.

Also known as El Castillo, the 25-meter-high pyramid is a solar clock, aligned to catch the rays of the setting sun on the spring and fall equinoxes, March 21 and September 22, respectively. Triangles of light and shadow form along the side of the north staircase and the figure of a snake appears, merging with the head of a stone serpent at the foot of the building, creating the illusion of a gigantic serpent slithering down from the heavens and across the ground towards the Sacred Cenote, a huge sinkhole or natural well that was a site of sacrificial rites.

The snake symbolizes Kukulcan (associated with Quetzalcoatl, a god worshipped by the ancient civilizations of central Mexico), the feathered serpent god, returning to earth to give hope to his followers and heralding the spring planting and fall harvest seasons for the Maya. A Mayan chronicle called Chilam Balam mentions Kukulcan as a leader who came out of the west and settled in Chichen Itza around AD 967 or 987, however his real identity is shrouded in mystery.

The Pyramid of Kukulcan was built some time between A.D. 650 and 800, with later modifications during the Itzae period of glory, possibly from A.D. 1000 to 1150. The earlier temples are deep inside the pyramid we see today. When archaeologists dug through tons of stone and earth to reach the inner sanctum, they discovered a chac mool statue, the enigmatic reclining figure with hands cupped to receive the heart of a sacrificial victim, guarding the entrance and a magnificent throne in the form of a red jaguar with jade spots and eyes. The jaguar was discovered with an offering of coral, sacrificial flint knives and a turquoise mosaic disc.

The pyramid also represents the ancient Mayan calendar as the number of terraces and wall panels coincides with the number of months in the year (18) and years in a calendar round (52), respectively, and the number of steps in the staircases, including the top platform, equals 365, the days in the year.

A short distance from the Great Plaza is the round tower known as El Caracol or the Observatory. It has a viewing platform

and wells, which were used by ancient astronomers to mirror starlight, and it was aligned to catch sunsets and moonsets on both equinoxes and to mark the course of Venus.

The snake of light and shadow is also visible the day before and after the equinox, cloud cover permitting. In 2012, it will be visible on September 22.

Chichen Itza is not the only Mayan ceremonial center in the Yucatan to have temples with solar, lunar or planetary alignments. The doorway of the Temple of the Seven Dolls at Dzibilchaltun (13 miles north of Merida) makes a perfect frame for the rising sun on the day of the Equinox. If you would like to see it you need to arrive early, at 5 a.m. Archaeologists also believe that El Palomar, a temple in the ancient city of Uxmal, the Yucatan’s other UNESCO World Heritage Site may also be aligned to catch the light and shadow on the spring and fall equinoxes.
