a physician of Marseilles who practised at Rome in the reign of Nero, A. D. 54-68, and introduced astrology into his medical practice. He acquired a large fortune, and is said by Pliny (Plin. Nat. 29.5) to have left at his death to his native city the immense sum of ten million sesterces (centies H. S.) or about 78,125l., after having spent nearly the same sum during his life in building the walls of the city.
