The Astrology of Vettius Valens

Vettius Valens of Antioch (120-some time after 173 CE) was a practising astrologer. His book, the Anthologies, survives in its original Greek, although it shows manifest signs of tampering up to the fifth century – this tampering, however, was by other astrologers who continued adding material to the text, keeping it up-to-date.
