Cales
Καλης
Cales (Καλης, Καλλης), a river of Bithynia, 120 stadia east of Elaeus. (Arrian, p. 14; and Marc. p. 70.) This seems to be the river which Thucydides (4.75) calls Calex (Κάληξ), at the mouth of which Lamachus lost his ships, which were anchored there, owing to a sudden rise of the river. Thucydides places the Calex in the Heracleotis, which agrees very well with the position of the Cales. Lamachus and his troops were compelled to walk along the coast to Chalcedon. Pliny (5.32) mentions a river Alces in Bithynia, which it has been conjectured, may be a corruption of Calex. There was on the river Cales also an emporium or trading place called Cales.
