Episode 89: 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. The book is a crucial source for ancient astrology as it was practised in the second century, as well as preserving many substantial citations from earlier, lost authorities on the prognosticatory art.

In this episode we discuss Valens’ fatalism, his book, his esoteric writing-practice, and his approach to astrology as a way of life. We also foreshadow his long afterlife in the East Roman and Islamicate esoteric-scientific traditions.
