Plutarch, De Herodoti malignitate
Goodwin, Ed.

Nor is this impious enough; but moreover, deriving the pedigree of Hercules from Perseus, he says that Perseus was an Assyrian, as the Persians affirm. ‘But the leaders,’ says he, ‘of the Dorians may appear to be descended in a right line from the Egyptians, reckoning their ancestors from before Danae and Acrisius.’ ¹ Here he has wholly passed by Epaphus, Io, Iasus, and Argus, being ambitious not only to make the other Herculeses Egyptians and Phoenicians, but to carry this also, whom himself affirms to have been the third, out of Greece to the barbarians. But of the ancient learned writers, neither Homer, nor Hesiod, or Archilochus, nor Pisander, nor Stesichorus, nor Alcman, nor Pindar, makes any mention of the Egyptian or the Phoenician Hercules, but all acknowledge this our own Boeotian and Argive Hercules.
