2. One of the followers of Erasistratus, who lived somewhat earlier than Apollonius of Memphis (Galen, Introd. 100.10, vol. xiv. p. 700), and therefore in the third century B. C., perhaps also in the fourth. He is by some modern writers supposed to be the same person as the physician mentioned above; but it is hardly probable that the same person could have been pupil to both Praxagoras and Erasistratus. He wrote a work on the names of the parts of the human body. (Galen, l.c.) It is not certain which of these two physicans is the person quoted by Oribasius (ibid. 45.11, p. 41), and Soranus. (De Arte Obstetr. p. 257, ed. Dietz.)
