The cult of Dionysus was strongly associated with satyrs, centaurs, and sileni, and its characteristic symbols were the bull, the serpent, tigers/leopards, ivy, and wine. The Dionysia and Lenaia festivals in Athens were dedicated to Dionysus, as well as the phallic processions. Initiates worshipped him in the Dionysian Mysteries, which were comparable to and linked with the Orphic Mysteries, and may have influenced Gnosticism. Orpheus was said to have invented the Mysteries of Dionysus.
