(Νατίσων; Natís ōn). River in Venetia (Ptol. 3,1,26) which rises in the Alpes Carnicae, flows below Forum Iulium (present-day Cividale), reaches the Turrus from the right (Plin. HN 3,126) and flows into the Laguna Veneta near Aquileia . It protected the east walls of Aquileia and formed a canal port there (Str. 5,1,8). At the estuary the river is nowadays called Natissa (as in Iord. Get. 42), but Natisone and Torre in the interior regions.
