As Michael Juhran discovers, Chichen Itza is a genuine architectural and mathematical masterpiece that the builders, the Mayas, achieved.
Hearts of the mathematician, the astronomer and architect leap for joy: 91 steps on each of the four sides of the pyramid temple of Kukulcan lead heavenwards. Taken together along with the single top step, they total 365 - exactly the number of days in the year.
At the equinoxes in March and September there appears a unique phenomenon - at sundown the shadows of the pyramid platforms glide, snakelike, down the steps and join together on the stone-carved snake heads at the foot of the pyramid.
On the ballgame field in what is arguably the best-known and most heavily-visited Mayan site, the Chichen Itza, yet another aspect of the Mayas comes to light: A bas-relief shows a decapitated pelote player. Blood flowing from his throat takes on the form of snakes.
Does the sacrificial victim represent the victor or the vanquished of the game? Neither scientists nor local experts can say for certain. To this day the Mayas are a mystery.
