Pherecydes of Leros (Ancient Greek: Φερεκύδης) was, according to the Suda, an ancient Greek historian from the island of Leros, who lived "before the seventy-fifth Olympiad" (480–477 BC), and wrote three works: On Leros (Περὶ Λέρου), On Iphigenia (Περὶ Ἰφιγενείας), and On the Festivals of Dionysus (Περὶ τῶν Διονύσου ἑορτῶν).[1] Although, the Suda considers them separately, he is possibly the same person as Pherecydes of Athens.[2]
