Carmentalia was the feast day (11 January and 15 January) of the Roman goddess Carmenta, an ancient oracle who later was deified by the Romans. She had her temple atop Capitoline Hill. Carmenta was invoked in it as Postvorta and Antevorta, epithets which had reference to her power of looking back into the past and forward into the future. The festival was chiefly observed by women.
