Dictionary of Greek and Roman Geography/Ascuris

ASCURIS (Esero), a lake in Thessaly in the range of Mt. Olympus. The castle Lapathus, which Livy describes as above the lake Ascuris, probably corresponds to the ancient castle near Rapsani. (Liv. xliv. 2; Leake, Northern Greece, vol. iii. pp. 349, 418.)
