(Εὐρυφῶν), a celebrated physician of Cnidos in Caria, who was probably born in the former half of the fifth century B. C., as Soranus (Vita Hippocr. in Hippocr. Opera, vol. iii. p. 851) says that he was a contemporary of Hippocrates, but older. The same writer says that he and Hippocrates were summoned to the court of Perdiccas, the son of Alexander, king of Macedonia; but this story is considered very doubtful, if not altogether apocryphal. [HIPPOCRATES.] He is mentioned in a corrupt fragment of the comic poet Plato, preserved by Galen (Comment. in Hippocr. "Aphor." 7.44. vol. xviii. pt. i. p. 149), in which, instead of ά̀πυος, Meineke reads ἂπυγος. He is several times quoted by Galen, who says that he was considered to be the author of the ancient medical work entitled Κνίδιαι γνῶμσι (Comment. in Hippocr. " De Morb. Vulgar. VI." 1.29. vol. xvii. pt. i. p. 886, where for ἰδίαις we should read Κνιδίαις), and also that some persons attributed to him several works included in the Hippocratic Collection (Comment. in Hippocr. " De Humor." i. prooem. vol. xvi. p. 3), viz. those entitled Περὶ Διαίτης Ὑγιεινῆς, de Salubri Victus Ratione (Comment. in Hippocr. " De Rat. Vict. in Morb. Acut." 1.17. vol. xv. p. 455), and Περὶ Διαίτης, de Victus Ratione. (De Aliment. Facult. 1.1. vol. vi. p. 473.) He may perhaps be the author of the second book Περὶ Νούσων, De Morbis, which forms part of the Hippocratic Collection, but which is generally allowed to be spurious, as a passage in this work (vol. ii. p. 284) is quoted by Galen (Comment. in Hippocr. " De Morb. Vulgar. VI." 1.29. vol. xvii. pt. i. p. 888), and attributed to Euryphon (see Littré's Hippocr. vol. i. pp. 47, 363); and in the same manner M. Ermerins (Hippocr. de Rat. Vict. in Morb. Acut. pp. 368, 369) conjectures that he is the author of the work Περὶ Γυναικείης Φύσιος, de Natura Muliebri, as Soranus appears to allude to a passage in that treatise (vol. ii. p. 533) while quoting the opinions of Euryphon. (De Arte Obstetr. p. 124.) From a passage in Caelius Aurelianus (de Morb. Chron. 2.10. p. 390) it appears, that Euryphon was aware of the difference between the arteries and the veins, and also considered that the former vessels contained blood. Of his works nothing is now extant except a few fragments, unless he be the author of the treatises in the Hippocratic Collection that have been attributed to him.
