AIUS LOCUTIUS, the name of a deity to whom the Romans erected an altar. The following circumstance gave occasion to this. One M. Ceditius, a plebeian, acquainted the tribunes that, in walking the streets by night, he had heard a voice over the temple of Vesta announcing to the Romans that the Gauls were coming against them. The intimation was, however, neglected; but after the truth was confirmed by the event, Camillus acknowledged this voice to be a new deity, and erected an altar to it under the name of Aius Locutus.
