Besides circumcision, the Americans practiced several other operations that bore an analogy to the operation of infibulation, a procedure common to the Orient and to early Europe, and so ancient that, like circumcision, its source is in the misty clouds of antiquity. It consisted in introducing a large ring, either of gold, silver, or iron, through an opening made into the prepuce, the free ends being then welded together. Females were treated likewise, the ring including both labia. In some countries an agglutination of the parts induced by some irritant or a cutting instrument answered the purpose among females. Dunglison mentions that the prepuce was first drawn over the glans, and then that the ring transfixed the prepuce in that position; that the ancients so muzzled the gladiators to prevent them from being enervated by venereal indulgence. The ancient Germans lived a life of chastity until their marriage, and to their observance of a chaste life can be attributed the superior physical development of the race, as both males and females were not only fully developed, but were not enervated by either sexual excess or inclinations before having offspring, which were necessarily robust and healthy. To obtain the same results in a nation given to indolence and luxury, and lax in its morality, some physical restraint was required, and we therefore find the practice of infibulation coming from the warm countries to the East. The ancients not only infibulated their gladiators to restrain them from venery, but they also subjected their chanters and singers to the same ordeal, as it was found to improve the voice; comedians and public dancers were also restrained from ruining their talents by the means of infibulation. In an old Amsterdam edition of Locke's "Essay on the Extent of the Human Understanding," there is a quotation from the voyages of Baumgarten, wherein he states having seen in Egypt a devout dervish seated in a perfect state of nature among the sand-hillocks, who was regarded as a most holy and chaste man for the reason that he did not associate with his own kind, but only with the animals. As this was by no means an uncommon case, it led the Greek monks, in Greece and Asia Minor, to resort to every expedient to protect their chastity; in some of the monasteries not only were the monks muzzled by the process of infibulation, but they even had rules that excluded all females, either human or animal, from within their convent,--a habit that still prevails among many of the convents of the Orient to this day,--that on Mount Athos especially, omitting the infibulation of the ancients.
