The study explores the existence and the meaning of a hero cult dedicated to Aiax Oileus on the part of Lokroi. This tradition involves a rehabilitation of the hero through the atonement of the violence perpetrated against Athena and Cassandra during the last night of Troy and is part of the propaganda produced by Lokroi Epizephyrioi in the years following the battle of Sagra. Aiax is portrayed as a hero with powers of healing, similar to Achilles: his new role culminates in the miraculous healing of the chief of Kroton army defetead in the battle of Sagra, wich took place in the island of Leuke in the presence of the royal couple, Achilles and Helen.
