(Πτολεμαῖος), a surgeon, one of whose medical formulae is quoted by Celsus (De Med. 6.7. 2, p. 126), and who must, therefore, have lived in or before the first century after Christ. He is perhaps the same person whose opinion on the cause of dropsy is quoted by Caelius Aurelianus (De Morb. Chiron. 3.8. p. 479), and who is called by him a follower of Erasistratus. Perhaps also he is the physician whose medical formulae are quoted by Asclepiades Pharmacion (ap. Galen. De Comepos. Medicam. sec. Loc. 2.2, vol. xii. p. 584; see also ibid. 4.7. p. 789, De Compos. Mlledicam. sec. Gen. 5.14, vol. xiii. pp. 849, 853.)
