Original Leaf from Galeno Ascripti Libri Qui Variam Artis Medicae, 1515

Doctor Galen was born in Pergamus, Greece between 129-200. During the 15th century, the medical profession changed his name to Galini or Galeno. He differed from most medical scientists of his time by practicing pathology instead of turning to teaching as did most of his colleagues. Although born in Greece, Galen practiced in Rome and left such an impression there that up to the 16th century, his books were considered to be the foremost on physiology and his ideas were accepted without question.
