Dionysius
2. A native of CYRTUS (Κυρτός) in Egypt, who was mentioned by Herennius Philo in his lost History of Medicine. Stephanus Byzantinus(s. v. Κύρτος calls him διάσημος ἰατρός. His date is uncertain, but if (as Meursius conjectures) he is the same person who is quoted by Caelius Aurelianus (De Morb. Chron. 2.13, p. 416), he may be supposed to have lived in the third century B. C. (Meursius, Dionysius, &c. in Opera, vol. v.)
