Bacchanalia
Bacchus was conscripted into the official Roman pantheon as an aspect of Liber, and his festival was inserted into the Liberalia. In Roman culture, Liber, Bacchus and Dionysus became virtually interchangeable equivalents. Thanks to his mythology involving travels and struggles on earth, Bacchus became euhemerised as a historical hero, conqueror, and founder of cities. He was a patron deity and founding hero at Leptis Magna, birthplace of the emperor Septimius Severus, who promoted his cult. In some Roman sources, the ritual procession of Bacchus in a tiger-drawn chariot, surrounded by maenads, satyrs and drunkards, commemorates the god's triumphant return from the conquest of India. Pliny believed this to be the historical prototype for the Roman Triumph.
