Messapus of Sicyon

Messapus (Ancient Greek: Μέσσαπος Messapos) was the ninth king of Sicyon in the Peloponnesus according to classical Greek mythography.

Mythology
Writers quoting Castor of Rhodes stated that he reigned over Sicyon for 47 years following Leucippus, and before Eratus. However, Pausanius omitted 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.
