Greeks of the Classical age accepted Mopsus as a historical figure, though the anecdotes concerning him bridge legend and myth.
He distinguished himself at the siege of Thebes; but he was held in particular veneration at the court of Amphilochus at Colophon on the Ionian coast of Asia Minor, adjacent to Caria.
His death is attributed by sources used by John Tzetzes to another mortification of the same nature: in this case, the two soothsayers, jealous of each other's fame, came to a different trial of their skill in divination.
Calchas confessed his inability to answer, whereupon Mopsus declared that she would be delivered on the morrow, and would bring forth ten young ones, of which only one would be a male.
[7] A bilingual (Hittite–Phoenician) inscription and a Hittitic tablet found in Turkey are independent non-Greek sources on Mopsos and the migration of Greeks in Asia Minor.
