The Cult
Vulcanus was worshipped at the Volcanal, an open-air precinct in the Roman Forum near the Comitium and the archaic Lapis Niger, one of the oldest cult sites in the city. The Volcanalia on 23 August called for public sacrifices, and the ritual included throwing living fish into a fire — an offering that acknowledged both his power over flame and his water-averting role. A flamen Volcanalis supervised his cult, and his temple outside the city walls in the Campus Martius stood beyond the pomerium, since fire was too dangerous to admit within the sacred boundary. Blacksmiths and metalworkers maintained private rites at their forges, making him a guild-patron as much as a state god.
