Dictionary of Greek and Roman Biography and Mythology/Leonidas 2.

LEO′NIDAS （Λεωνίδας), physician who was a native of Alexandria, and belonged to the sect of the Episynthetici (Pseudo-Galen, Introd. c. 4. vol. xiv. p. 684; Cael. Aurel. ''De Morb. Acut.'' ii. 1, p. 75). As he is quoted by Caelius Aurelianus (l. c.), and himself quotes Galen (ap. Aët. iv. 2, 11, p. 688), he probably lived in the second and third centuries after Christ. Of his writings, which appear to have chiefly related to surgical subjects, nothing remains but some fragments preserved by Aëtius (pp. 241, 397, 686, 687, 688, 689, 691,692, 736, 741, 743, 799, 800, 802) and Paulus Aegineta (iv. 59,p. 534, vi. 32, 44, 64, 67, 78, pp. 562, 569, 578, 580, 585), from which we may judge that he was a skilful practitioner.
