Messapus of Sicyon
Messapus was the ninth king of Sicyon in the Peloponnesus according to classical Greek mythography. Writers quoting Castor of Rhodes state that he reigned there for 47 years following Leucippus, and before Eratus.
However, Pausanius omits this king Messapus, alleging that the throne passed directly from Leucippus, who had no male heir, to his grandson Peratus.
According to Strabo, Messapio in Boeotia, and later Messapia in southeastern Italy, derived their names from this Messapus.
