Micythus, son of Choerus, was a tyrant of Rhegium (modern Reggio Calabria) in the 5th century BC.He was at first a slave in the service of Anaxilas, tyrant of Rhegium, but gradually rose to so high a place in the confidence of his master, that Anaxilas at his death (476 BC) left him guardian of his infant sons, with charge to hold the sovereign power in trust for them, until they should attain to manhood.The administration of Micythus appears to have been both wise and vigorous, so that he conciliated the affections of his subjects, and held the government both of Rhegium and Messana, undisturbed by any popular commotions.
