(), 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. [W.A.G]
