Greek physician, who lived at Rome. We possess two treatises by him, each in four books, in the Ionic dialect: On the Causes and Indications of Acute and Chronic Diseases, and On their Treatment. His work was founded on that of Archigenes; like him, he belonged to the eclectic school, but did not ignore the theories of the Pneumatics, who made the heart the seat of life and of the soul.
