By the smaller offerings of Micythus, that were made by Dionysius, are some of the exploits of Heracles, including what he did to the Nemean lion, the Hydra, the Hound of Hell, and the boar by the river Erymanthus. These were brought to Olympia
by the people of Heracleia when they had overrun the land of the Mariandynians, their foreign neighbors. Heracleia is a city built on the Euxine sea, a colony of Megara
, though the people of Tanagra
joined in the settlement.
