ISMENUS is a river of Boeotia, that washes the walls of Thebes. It was formerly called the foot of Cadmus, upon this occasion. When Cadmus had slain the dragon which kept the fountain of Mars, he was afraid to taste of the water, believing it was poisoned; which forced him to wander about in search of another fountain to allay his thirst. At length, by the help of Minerva, he came to the Corycian den, where his right leg stuck deep in the mire. And from that hole it was that, after he had pulled his leg out again, sprung a fair river, which the hero, after the solemnity of his sacrifices performed, called by the name of Cadmus’s foot.

Some time after, Ismenus, the son of Amphion and Niobe, being wounded by Apollo and in great pain, threw himself into the said river, which was then from his name called Ismenus;—as Sostratus relates in his Second Book of Rivers.
