Sebinus Lacus

SEBI´NUS LACUS (Laogo d'Iseo), a large lake in the N. of Italy, at the foot of the Alps, formed by the waters of the river Ollius (Oglio), which after flowing through the land of the Camuni (the Val Camonica), are arrested at their exit from the mountains and form the extensive lake in question. It is not less than 18 miles in length by 2 or 3 in breadth, so that it is inferior in magnitude only to the three great lakes of Northern Italy; but its name is mentioned only by Pliny (Plin. Nat. 2.103. s. 106, 3.19. s. 23), and seems to have been little known in antiquity, as indeed is the case with the Lago d'Iseo at the present day. It is probable that it derived its name from a town called Sebum, on the site of the modern Iseo, at its SE. extremity, but no mention of this name is found in ancient writers. (Cluver, Ital. p. 412.)

Now the Lago Seo; a lake in Gallia Cisalpina (Pliny H. N. ii. 224).
