Leo the Physician, Epitome on the Nature of Man

Leo of Constantinople is a ninth-century physician. Renehan printed the Synopsis on the Nature of Man in Corpus of Greek Medical Writers 10.4 (Berlin, 1969); it is an epitome of human nature. A second work is his Synopsis of Medicine, addressed to Georgios: not once or twice but often Georgios asked him to go over in brief the medical theorems learned in the lectures. Book 1 is fevers (synochos, tertian, quartan, hectic, marasmus); later books run the head, eyes, throat, gut, stone, and inflammations, each with cause, signs, and treatment, citing Galen and Hippocrates.

He is a Byzantine medical writer, not a second-century philosopher: Constantinople was not yet founded.

Leo is the ninth-century physician, author of an epitome of human nature and a handbook that runs from fevers to surgery.
