  • G. J. Toomer


Tiberius Claudius Thrasyllus, of *Alexandria (1), astrologer (d. 36 ce), owed his great reputation to the emperor *Tiberius, who, meeting him in *Rhodes, brought him to Rome, trusted his predictions, and made him a Roman citizen. Thrasyllus produced a distinguished family, including his astrologer son Ti. *Claudius Balbillus. His interests were wide, including music (he wrote Περὶ τῶν ἑπτὰ τόνων, (‘On the seven tones’) and philosophy (the division of *Plato (1)'s dialogues into tetralogies is ascribed to him). He is frequently cited by *Vettius Valens and other astrologers. See astrology.
