Right-bank tributary of the Padus (modern Po), into which it flows at Placentia (Plin. HN 3,118), modern Trebbia; it rises in the Ligurian Appenninus. It was on the T. that in 218 BC the first fighting between the Romans and Hannibal [4] took place (Pol. 3,66-74; Liv. 21,52-56). In its valley are the sacrarium Minervae Medicae Cabardiacensis and the Bobbio monastery founded in 612 by Saint Columbanus.
