The Code of Hammurabi was found among the cuneiform tablets of the library of Ashurbanipal. It is now in the Louvre. It was first published in Scheil, "Textes élamites-sémitiques. Deuxième série: accompagné de 20 planches hors texte," Mémoires de la Délégation en Perse, Paris, 1902, 4, 4-162. The Code mentions the fees payable to a physician following successful treatment; these varied according to the station of the patient. Similarly, the punishment for the failure of an operation is set out. At least this shows that in Babylon 4,000 years ago the medical profession had advanced far enough in public esteem to warrant the payment of adequate fees.
