There are several distinct figures in Greek mythology named Manto (Greek: Μαντώ), the most prominent being the daughter of Tiresias. The name Manto derives from Ancient Greek , "seer, prophet".
Manto was the daughter of the prophet Tiresias and mother of Mopsus. Tiresias was a Theban oracle who, according to tradition, was changed into a woman after striking a pair of copulating snakes with a rod, and was thereafter a priestess of Hera.
During the War of the Epigoni, a later myth relates, Manto was brought to Delphi as a war prize. Apollo sent her to Colophon to find an oracle devoted to him. She married Rhacius and gave birth to Mopsus (although by some accounts Apollo was the father). According to the Bibliotheca, she had two children by Alcmaeon-- Amphilochus and Tisiphone. In Roman myth, Manto went to Italy and gave birth to Ocnus (father: Tiberinus, the genius of the river Tiber). Ocnus founded Mantua and named it after his mother.
It was said that Manto's abilities in prophecy were much greater than her father's.
