ペルシア人
A Greek folk etymology connected "Perseus" to the name of the Persian people, whom they called the "Pérsai" (from Old Persian "Pārsa" "Persia, a Persian"). The native name of this people, however, has always had an "-a-" in Persian. Herodotus recounts this story, devising a foreign son, Perses, from whom the Persians took the name. Apparently also the Persians knew the story, as Xerxes tried to use it to bribe the Argives during his invasion of Greece, but ultimately failed to do so.
