Dioscoriaes Fedanius
Dioscoriaes Fedanius, a Greek physician of the first century A.D., was a native of Cilicia. He wrote a valuable work upon Materia Medica, and his researches upon botany, in five books, have much merit, and are still of high authority in the East. He was a soldier, and travelled in Asia Minor, Greece, and Spain, studying natural history. The authorship of a treatise upon poisons, sometimes ascribed to him, is disputed.
