​ACRON, a Greek physician, born at Agrigentum in Sicily, was contemporary with Empedocles, and must therefore have lived in the 5th century before Christ. The successful measure of lighting large fires, and purifying the air with perfumes, to put a stop to the plague in Athens (430 B.C.), is said to have originated with him; but this has been questioned on chronological ​grounds. Suidas gives the titles of several medical works written by him in the Doric dialect.
