Note 516 — Chapter III · SENECA AND PTOLEMY: NATURAL DIVINATION AND ASTROLOGY
Reading edition
Indeed, Hephaestion’s first two books are nothing but Ptolemy repeated. About contemporary with Ptolemy seems to have been Vettius Valens whose astrological work is extant: Vettius Valens, Anthologiarum libri primum edidit Guilelmus Kroll, Berlin, 1908. See also CCAG passim concerning both Hephaestion and Vettius Valens, and Engelbrecht, Hephästion von Theben und sein astrologisches Compendium, Vienna, 1887.
