ティトゥス・タティウス
The first mention of a ritual connection between Vulcan and Vesta is the lectisternium of 217 BC. Other facts that seem to hint at this connection are the relative proximity of the two sanctuaries and Dionysius of Halicarnassus's testimony that both cults had been introduced to Rome by Titus Tatius to comply with a vow he had made in battle. Varro confirms the fact.
