Of Genoa, flows by Bobbio, and joins the Po a few miles above Piacenza; (3) the Nure, a few miles east of the preceding; (4) the Taro, a more considerable stream; (5) the Parma, flowing by the city of the same name; (6) the Enza; (7) the Secchia, which flows by Modena; (8) the Panaro, a few miles to the east of that city; (9) the Reno, which flows by Bologna, but instead of holding its course till it discharges its waters into the Po, as it did in Roman times, is turned aside by an artificial channel into the Po di Primaro.
It is situated in a damp, low plain in the open country in the south side of the valley of the Po, between the Secchia to the west and the Panaro to the east.
High; in the basement may be seen the wooden bucket captured by the Modenese from the Bolognese in the affray at Zappolino (1325), and rendered famous by Tassoni's Secchia Rapita.
From the northern slopes many rivers and streams run north and north-north-east into the Po, the Secchia (Secia) and Panaro (Scultenna) being among the most important, while farther east most of the rivers are tributaries of the Reno (anc. Rhenus).
