Izapa Stela 4 depicts a bird dance, which has a king being transformed into a bird. The scene is most likely connected with the Principle Bird Deity. This transformation could symbolize shamanism and ecstasy, meaning the shaman-ruler used hallucinogens to journey to another world. The type of political system that was in place at Izapa is still unknown, though Stela 4 could suggest that a shaman was in charge. This shaman-ruler would serve the role of both the political and religious leader.
