a Roman divinity, who had a temple near the Porta Capena, and who was believed to have received his name from having induced Hannibal, when he was near the gates of the city, to return (redire) southward (Fest. p. 282, ed. Muller). A place on the Appian road, near the second mile-stone from the city, was called Campus Rediculi (Plin. Nat. 43.60.122 ; Propert. 3.3, 11). This divinity was probably one of the Lares of the city of Rome, for, in a fragment of Varro (apud Non. p. 47), he calls himself Tutanus, i. e., the god who keeps safe.
