This altar is also known as the Altar of Unconquered Hercules. The altar was located in the Forum Boarium. This was Hercules' earliest cult-center. This altar was made by King Evander after Hercules slayed Cacus, who had stolen Hercules cattle. The festival day was August 12, and in 312 BC, the state took over the altar. Women were not allowed in the cult, dogs were not allowed in the precinct. Remains of the pavement survive in the crypt behind the Church of S. Maria in Cosmedin.
