In the story of the cure of Saul's blindness Luke says in the Acts that his blindness fell from him like scales. The figure is a typically medical one. The word for fall that is used is, as was pointed out by Hobart ("Medical Language of St. Luke," Dublin, 1882), exactly the term that is used for the falling of scales from the body. The term for scales is the specific designation of the particles that fall from the body during certain skin diseases or after certain of the infectious fevers, as in scarlet fever. Hippocrates and Galen have used it in many places. It is distinctively a medical word. In the story of the vision of St. Peter, told also in the Acts, the word _ecstasis_, from which we derive our word ecstasy, is used. This is the only word St. Luke uses for vision and he alone uses it. This term is of constant employment in a technical sense in the medical writers of St. Luke's time and before it. When the other evangelists talk of lame people they use the popular term. This might mean anything or nothing for a physician. Luke uses one of the terms that is employed by physicians when they wish to indicate that for some definite reason there is inability to walk. In the story of the Good Samaritan there are some interesting details that indicate medical interest on the part of the writer. It is Luke's characteristic story and a typical medical instance. He employs certain words in it that are used only by medical writers. The use of oil and wine in the treatment of the wounds of the stranger traveller was at one time said to indicate that it could not have been a physician who wrote the story, since the ancients used oil for external applications in such cases but not wine. More careful search of the old masters of medicine, however, has shown that they used oil and wine not only internally but externally. Hippocrates, for instance, has a number of recommendations of this combination for wounds. It is rather interesting to realize this, and especially the wine in addition to the oil, because wine contains enough alcohol to be rather satisfactorily antiseptic. There seems no doubt that wounds that had been bathed in wine and then had oil poured over them would be likely to do better than those which were treated in other ways. The wine would cleanse and at least inhibit bacterial growth. The subsequent covering with oil would serve to protect the wound to some degree from external contamination.
