It was known in ancient times as Supunna by Umbri and later in Latin as Tinia[1] [2] and is mentioned by Dante Alighieri in the Canto XI of the Paradise.

It is the main tributary of the Chiascio, in the Tiber basin [Wikidata].

[3] Its spring is on the slopes of the Monte Pennino, at 649 metres (2,129 ft), in the territory of Nocera Umbra.

Topino's tributaries include the Menotre, the Clitunno (known as Timia past its confluence with Marroggia creek) and the Ose.

After passing through the comuni of Valtopina, Foligno, Bevagna, Cannara and Bettona, it joins the Chiascio at Passaggio.
