PLAVIS
PLAVIS(Piave), one of the most considerable rivers of Venetia, which has its sources in the Julian Alps, flows by the walls of Belluno(Belunum), and falls into the Adriatic sea between Veniceand Caorle. Though one of the largest rivers in this part of Italy, it is unaccountably omitted by Pliny (Plin. Nat. 3.18. s. 22), who mentions the much smaller streams of the Silis and Liquentia on each side of it; and its name is not found in any author earlier than Paulus Diaconus and the Geographer of Ravenna. (P. Diac. 2.12; Geogr. Rav. 4.36.)
