Aretades of Cnidus (Greek, Modern (1453-);: Ἀρητάδης ὁ Κνίδιος) was an ancient Greek historian from the city of Cnidus. He wrote a work on the history of Macedon (Greek, Modern (1453-);: Μακεδονικά) in three books at least, and another on the history of various Greek islands (Greek, Modern (1453-);: Νησιωτικά) in two books at least.[1] It is uncertain whether the particular Aretades referred to by Porphyry as the author of a work Peri Sumptoseos (Greek, Modern (1453-);: Περί συμπτώσεως), is the same as Aretades of Cnidus or not.[2]
