a physician, who was a native of Sicily and a pupil of Asclepiades of Bithynia, and who therefore lived in the first century B. C. (Steph. Byz. s. v. Δυρράχιον.) He is probably the same person who is quoted by Caelius Aurelianus by the name of Titus only, and who wrote a work On the Soul and another On Chronic Diseases, consisting of at least two books. (Acut. Morb. 2.29, p. 144; Morb. Chron. 1.5, p. 339.)
