Quadrifrons
A surname of Janus. It is said that after the conquest of the Faliscans an image of Janus was found with four foreheads. Hence a temple of Janus Quadrifrons was afterwards built in the Forum transitorium, which had four gates. The fact of the god being represented with four heads 人 is considered by the ancients to be an indication of his being the divinity presiding over the year with its four seasons.
