a physician of Tarsus in Cilicia (Galen. De Compos. Medical. sec. Loc. 9.5. vol. xiii. p. 295), who must have lived in or before the first century after Christ, as he is mentioned by Archigenes. (ap. Galen. ibid. 3.1. vol. xii. p. 623.) He was perhaps tutor to Criton (Galen, ibid. 5.3. vol. xii. p. 828) and Asclepiades Pharmacion (ibid. vol. xiii. pp. 648, 746, 846, 850, 852, 857, 969), unless (as is not unlikely) the term ὁ καθηγητής be used merely as a sort of honorary title. Fabricius says (Bibl. Graec. vol. xiii. p. 310, ed. vet.) that he was tutor to Galen, but it is probable that in the passage referred to (vol. xiii. pp. 524,
828
539) Galen is quoting the words of Asclepiades Pharmacion. His medical formulae are also several times quoted by Aetius (3.4. 42, p. 604, 4.2. 3, p. 685, 4.3. 3, 9, 14, pp. 740, 745, 762, 763), but none of his writings are extant. If he be the same person quoted by Caelius Aurelianus (De Mort. Chron. 2.1, 7, pp. 365, 386, 4.3, p. 522), he wrote a work on chronic diseases (Tardae Passiones) consisting of at least four books.
