Iollas, Iolaus
or IOLAS (
Ἰόλλας,
Ἰόλαος, or
Ἰόλας), a writer on materia medica, born in Bithynia, who was probably a contemporary of Heracleides of Tarentum, or a little anterior to him, in the third century B. C., as he is mentioned in company with him by Dioscorides. (
De Mat. Med. i. Praef. vol. i. p. 2.)
He is mentioned also by Celsus (
De Medic. 5.22, p. 93), Pliny (
Plin. Nat. 20.73,
76), Galen (
De Antid. 1.2, vol. xiv. p. 7), St. Epiphanius (
Adv. Haeres. 1.1. 3. p. 3.), and the scholiast on Nicander (
Ther. 5.683), but nothing is known of the events of his life, nor are any of his writings preserved.
