Rhetorius

Rhetorius of Egypt was the last major classical astrologer from whom we have any excerpts. He lived in the sixth or early seventh century, in the early Byzantine era. He wrote an extensive compendium in Greek of the techniques of the Hellenistic astrologers who preceded him, and is one of our best sources for the work of Antiochus of Athens. Although no intact original manuscript survives of his work, we do have several late Byzantine versions of it.
