Mexico is one of the cradles of humanity and was home to some of the world's great civilisations. Everyone knows about the Aztec and the Maya, but these are just two of the many peoples who inhabited the region. In this episode we look at the earliest cities in Mesoamerica including the Olmec and the Zapotec. We will also discuss the ball game - the strange sport which was ubiquitous in the area, and which sometimes resulted in the sacrifice of its participants.
