1. Of Cnidos, has sometimes been confounded with the celebrated Stoic philosopher of the same name, who, however, lived about a century later.
He was the son of Erineus (D. L. 8.89
), and must have lived in the fourth century B. C., as he was a contemporary of Praxagoras (Cels. De Med.
Praef. lib. i. p. 5; Plin. Nat. 26.6
), a pupil of Eudoxus of Cnidos and Philistion (Diog. Laert. l.c.
), father of Chrysippus the physician to Ptolemy Soter (id. 7.186), and tutor to Erasistratus (id. l.c. ; Plin. Nat. 29.3
; Galen, De Ven. Sect. adv Erasistr.
100.7, vol. xi. p. 171), Aristogenes (id. De Ven. sect. adv. Erasistr. Rom. Deg.
100.2, et De Cur. Rat. per Ven. Sect.
100.2, vol. xi. pp. 197, 252), Medius (id. ibid.
), and Metrodorus. (Sext. Empir. cont. Mathem.
1.12, p. 271, ed. Fabric.)
He accompanied his tutor Eudoxus into Egypt (D. L. 8.87
), but nothing more is known of the events of his life.
He wrote several works, which are not now extant, and Galen says (De Vcn. Sect. adv. Ertisislr. Rom. Deg.
100.5, vol. xi. p. 221), that even in his time they were in danger of being lost. Several of his medical opinions are, however, preserved by Galen, by whom he is frequently quoted and referred to. (De Ven. Sect. adv. Erasistr., &c.,
vol. xi. pp. 149, &c., 171, &c., 197, 221, &c.)
