a physician who is quoted by Andromachus (ap. Galen. De Compos. Medicam. sec. Loc. 9.4, De Compos. Medicam. sec. Gen.2.15, 5.13, vol. xiii. pp. 281, 533, 842), and who must therefore have lived in or before the first century after Christ. He is by some persons supposed to have been one of Galen's tutors, but this is undoubtedly a mistake; as, besides the chronological difficulty, it is probable that in the passage which has given rise to this opinion (De Compos. Medical. sec. Gen. 5.14, vol. xiii. p. 852) Galen is quoting the words of Asclepiades Pharmacion, and not speaking in his own person; and also that the term ὁ καθηγητής is used merely as a sort of honorary title [comp. Lucius, p. 1127]. He is quoted also by Marcellus Empiricus, De Medicam. 100.29, p. 378.
