One religious dedication survives of the guild of the stuppatores, the flax workers. The discovery was reported in 1870, but the precise place of discovery is unknown. It is not clear what the men dedicated. The feminine ornatam could go with aediculam and aram, but aedem or scholam seem more likely, so a shrine or temple, or a guild seat.
