Asopus

Asopus (/əˈsoʊpəs/; Ancient Greek: Ἀ̄σωπός Āsōpos) is the name of four different rivers in Greece and one in Turkey. In Greek mythology, it was also the name of the gods of those rivers. Zeus carried off Aegina, Asopus' daughter, and Sisyphus, who had witnessed the act, told Asopus that he could reveal the identity of the person who had abducted Aegina, but in return Asopus would have to provide a perennial fountain of water at Corinth, Sisyphus' city. Accordingly, Asopus produced a fountain at Corinth, and pursued Zeus, but had to retreat for fear of Zeus' terrible thunderbolt.
