Though Sak Tz’i’ was nowhere near as powerful as more famous Mayan kingdoms such as Chichen Itza and Palenque, it can still reveal things we never knew about Mayan culture. Golden That court was used for ceremonial ball games in which the players would use their hips and shoulders to bounce a heavy rubber ball back and forth. Plaza Muk’ul Ton was the city center where people gathered for religious, political and recreational purposes. The royal family lived and were possibly buried there.
Sak Tz’i’ could also tell us how lesser Maya kingdoms put up with those that were more powerful. Sculptures like the tablet found by the vendor tell mythological stories, such as a legendary flood, and keep records of actual battles and the births, lives, and deaths of kings such as K’ab Kante’. Also inscribed in the stone were their beliefs that kings could merge with or even transform into gods.
