The Platform of Venus Chichen Itza Yucatan Mexico. The platform of Venus is a square shaped platform with steps on all four sides each with balustrades ending in serpents heads and whose bodies are represented in the upper section as being plumed and sinuous in form and combined with fish figures. Mythical creatures, a combination of jaguar eagle serpent and human forms, adorn the centre of the side panels. In each corner there are glyphs associated with the planet Venus. It was probably used for ceremonial purposes.
