Pherecydes of Leros (Ancient Greek: Φερεκύδης) was an ancient Greek historian from the Aegean island of Leros.[1] He lived during the 5th century BCE and wrote three texts: "On Leros" (Περὶ Λέρου), "On Iphigenia" (Περὶ Ἰφιγενείας), and "On the Festivals of Dionysus" (Περὶ τῶν Διονύσου ἑορτῶν).[1] Pherecydes of Leros is maybe the same person as Pherecydes of Athens even though the Suda treats them as separate individuals.[2]
