By gradual evolution and the progress of society, the cultivation of the ground and the need of menials, warriors found some other use for their prisoners taken in strife besides merely cutting off the phallus as a trophy; these prisoners began to have some intrinsic value. From this a change came about; the warrior instinct, however, still claimed that the vanquished, even if a slave, should still convey or carry some sign of servitude. The original idea of the ablation of the phallus was to emasculate the victim; investigation developed the idea that the same object could be accomplished by castration, an operation which also finally reached a tolerable state of perfection through different stages of evolution, it first being performed by a complete removal of the whole scrotum and contents. This operation, with the ignorance of the times in regard to stopping haemorrhage, was, however, accompanied by a large mortality, and it finally evolved into the simple removal of the gland, or its obliteration by pressure or violence. Bergmann conveys the idea that circumcision was at one time the indestructible marking and the distinctive feature of the slave, the mind of the period not being able to emancipate itself from the idea that the genitals must in some manner be mutilated, not being able to conceive any other degrading mark of manhood which barbarians felt they must inflict on slaves. The generally accepted idea in regard to the physical mutilation of captives taken in war, or that some token from the body of the vanquished must be carried off by the victor, has not only the support of tradition and monumental sculptured evidence, but its practice is still in vogue among many races. Among the ancient Scythians, only the warriors who returned from the battle or foray with the heads of the enemy were entitled to a share in the spoils. Among the modern Berbers it is still a practice for a young man, on proposing marriage, to exhibit to his prospective father-in-law the virile members of all the enemies he has overcome, as evidence of his manhood and right to the title of warrior. The Abyssinians and some of the negro tribes on the Guinea coast still follow the custom of securing the phallus of a fallen foe. However barbarous this practice may seem, its actual performance is only secondary, the primary motive being that the warrior wished to prove that he had been there, engaged in actual strife, and that his enemy had been overcome. The writer remembers that, after one of the battles in the West during the late war, many letters arrived in his locality with pieces of the garments or locks of the hair of the unfortunate Confederate general, Zollikoffer, who had been slain in the battle; a disposition in the warrior, seemingly still existing, such as animated the old Egyptians. On an old Egyptian monument,--that of Osymandyas,--Diodorus noticed a mural sculpture, a _bas-relief_ representing prisoners of war, either in chains or bound with cords,
