ISEO, LAKE OF (the Lacus Sebinus of the Romans), a lake in Lombardy, N. Italy, situated at the southern foot of the Alps, and between the provinces of Bergamo and Brescia. It is formed by the Oglio river, which enters the northern extremity of the lake of Lovere, and issues from the southern end at Sarnico, on its way to join the Po. The area of the lake is about 24 sq. m., it is 1712 m. in length, and 3 m. wide in the broadest portion, while the greatest depth is said to be about 984 ft. and the height of its surface above sea-level 607 ft. It contains one large island, that of Siviano, which culminates in the Monte Isola (1965 ft.) that is crowned by a chapel, while to the south is the islet of San Paolo, occupied by the buildings of a small Franciscan convent now abandoned, and to the north the equally tiny island of Loreto, with a ruined chapel containing frescoes. At the southern end of the lake are the small towns of Iseo (15 m. by rail N.W. of Brescia) and of Sarnico. From Paratico, opposite Sarnico, on the other or left bank of the Oglio, a railway runs in 614 m. to Palazzolo, on the main Brescia-Bergamo line. Towards the head of the lake, the deep wide valley of the Oglio is seen, dominated by the glittering snows of the Adamello (11,661 ft.), a glorious prospect. Along the east shore (the west shore is far more rugged) a fine carriage road rims from Iseo to the considerable town of Pisogne (1312 m.), situated at the northern end of the lake, and nearly opposite that of Lovere, on the right bank of the Oglio. The portion of this road some way S. of Pisogne is cleverly engineered, and is carried through several tunnels. The lake’s charms were celebrated by Lady Mary Wortley-Montagu, who spent ten summers (1747–1757) in a villa at Lovere, then much frequented by reason of an iron spring. The lake has several sardine and eel fisheries. (W. A. B. C.)
