(Φαών), one of the most ancient of the Greek physicians, who must have lived in or before the fifth century B. C., as he was either a contemporary or predecessor of Hippocrates. He was one of the persons to whom some of the ancient critics attributed the treatise Περὶ Διαίτης ʽπριεινῆς, De Salubri Vic/ts Ratione, which forms part of the Hippocratic Collection. [HIPPOCRATES, p. 486a.] (Galen, Cozimment in Hippoer. "De Vict. Rat. in Morb. Acut." 1.17, vol. xv. p. 455.)
