One of the mythical kings of Alba, son of Capetus, and father of Agrippa, is said to have
been drowned in crossing the river Albula, which was hence called Tiberis. The name is thus
that of the personified Tiber who was solemnly invoked by the Romans (Cic. N. D. iii. 20, 52
). He had a shrine on the Insula Tiberina.
