[Essence and significance of surgery. Part I -- Birth of surgery: determining factors and contexts].
The author intends to particularly analyse the origin of Surgery as regards its deterministic factors and contexts, resounding the essence and the meaning of Surgery itself. The primary core of the surgical practice dates back to Prehistoric Times, when, driven by his self-preservation instinct, the cave man, when suffering from some trauma, performed on himself a series of more or less immediate "actions" in order to remain healthy. At the same time, a second meaningful nucleus of the surgical experience rises contiguously to the operations the Prehistoric Man performed on another member of his clan. The third stage of this ongoing process, coincident with the origin of surgery in the strict sense of the word, goes back to the tribal context: in fact, in this social organisation only one member of the group was specifically assigned to treat diseases, based on group regulations. For the mediterranean area, the chronological development of this evolution is likely to have started 250,000 years ago in connection with the experience initially of Neanderthal Man and subsequently Cro-Magnon Man in Pleistocene and Holocene of the Quarternary Era respectively, and it could have finished at the beginning of the Neolithic, when the "ancient civilization" of the Mediterranean Basin arose in approximately 10,000 B.C.
