The influence of Arabian medicine on modern medicine can, perhaps, best be judged from the number of words in our modern nomenclature, which, though bearing Latin forms, often with suggestion of Greek origins, still are not derived from the old Latin or Greek authors, but represent Arabic terms translated into Latin during the Renaissance period. Hyrtl, without pretence of quoting them all, gives a list of these which is surprising in its comprehensiveness. For instance, the mediastinum, the sutura sagittalis, the scrobiculus cordis, the marsupium cordis, the chambers of the heart, the velum palati, the trochanter, the rima glottidis, the fontanelles, the alae of the nose, all have their present names, not from original Latin expressions, but from the translation of Arabic terms. For all such words the Greeks and Romans have quite other expressions, in which the sense of our modern terms is not contained. This has given rise to many misunderstandings, and to many attempts in the modern times to return to the classic terminology rather than preserve what in many cases are the barbarisms introduced through the Arabic, but it is doubtful whether any comprehensive reform in the matter can be effected, so strongly entrenched in medical usage have these terms now become. Freind, in his "History of Medicine," already cited, calls attention to the fact that the Arabs had an unfortunate tendency to change by addition or subtraction of their own views the authors that they studied, and wished to translate to others. This seems to have been true even of some of the most distinguished of them. Of course, the idea of preserving an author's text untouched, and making it clear just where note and commentary came in, had not yet come to men's view, but quite apart from this the Arabs apparently often tried to gain acceptance for their own ideas by having them masquerade as the supposed ideas of favorite classic authors. Another unfortunate tendency among the Arabs was their liking for the discussion of many trivial questions. Hyrtl, in his volume on "Arabian and Hebrew Words in Anatomy,"[6] declares that it is almost incredible how earnestly some trivial questions in anatomy and physiology were discussed by the Arabs. He gives some examples. Why does no hair grow on the nose of men? Why does the stomach not lie behind the mouth? Why does the windpipe not lie behind the esophagus? Why are the breasts not on the abdomen? Why are not the calves on the anterior portion of the legs? Even such men as Rhazes and Avicenna discuss such questions.
