Three conditions have favored the extreme prevalence of bestiality: (1) primitive conceptions of life which built up no great barrier between man and the other animals; (2) the extreme familiarity which necessarily exists between the peasant and his beasts, often combined with separation from women; (3) various folk-lore beliefs such as the efficacy of intercourse with animals as a cure for venereal disease, etc.[[43]]

The beliefs and customs of primitive peoples, as well as their mythology and legends, bring before us a community of man and animals altogether unlike anything we know in civilization. Men may become animals and animals may become men; animals and men may communicate with each other and live on terms of equality; animals may be the ancestors of human tribes; the sacred totems of savages are most usually animals. There is no shame or degradation in the notion of a sexual relationship between men and animals, because in primitive conceptions animals are not inferior beings separated from man by a great gulf. They are much more like men in disguise, and in some respects possess powers which make them superior to men. This is recognized in those plays, festivals, and religious dances, so common among primitive peoples, in which animal disguises are worn.[[44]] When men admire and emulate the qualities of animals and are proud to believe that they descend from them, it is not surprising that they should sometimes see nothing derogatory in sexual intercourse with them.[[45]]

A significant relic of primitive conceptions in this matter may perhaps be found in the religious rites connected with the sacred goat of Mendes described by Herodotus. After telling how the Mendesians reverence the goat, especially the he-goat, out of their veneration for Pan, whom they represent as a goat ("the real motive which they assign for this custom I do not choose to relate"), he adds: "It happened in this country, and within my remembrance, and was indeed universally notorious, that a goat had indecent and public communication with a woman."[[46]] The meaning of the passage evidently is that in the ordinary intercourse of women with the sacred goat, connection was only simulated or incomplete on account of the natural indifference of the goat to the human female, but that in rare cases the goat proved sexually excitable with the woman and capable of connection.[[47]] The goat has always been a kind of sacred emblem of lust. In the middle ages it became associated with the Devil as one of the favorite forms he assumed. It is significant of a primitively religious sexual association between men and animals, that witches constantly confessed, or were made to confess, that they had had intercourse with the Devil in the shape of an animal, very frequently a dog. The figures of human beings and animals in conjunction carved on temples in India, also seem to indicate the religious significance which this phenomenon sometimes presents. There is, indeed, no need to go beyond Europe even in her moments of highest culture to find a religious sanction for sexual union between human beings, or gods in human shape, and animals. The legends of Io and the bull, of Leda and the swan, are among the most familiar in Greek mythology, and in a later pictorial form they constitute some of the most cherished works of the painters of the Renaissance.

As regards the prevalence of occasional sexual intercourse between men or women and animals among primitive peoples at the present time, it is possible to find many scattered references by travelers in all parts of the world. Such references by no means indicate that such practices are, as a rule, common, but they usually show that they are accepted with a good-humored indifference.[[48]]

Bestiality is very rarely found in towns. In the country this vice of the clodhopper is far from infrequent. For the peasant, whose sensibilities are uncultivated and who makes but the most elementary demands from a woman, the difference between an animal and a human being in this respect scarcely seems to be very great. "My wife was away too long," a German peasant explained to the magistrate, "and so I went with my sow." It is certainly an explanation that to the uncultivated peasant, ignorant of theological and juridical conceptions, must often seem natural and sufficient.

Bestiality thus resembles masturbation and other abnormal manifestations of the sexual impulse which may be practiced merely faute de mieux and not as, in the strict sense, perversions of the impulse. Even necrophily may be thus practiced. A young man who when assisting the grave-digger conceived and carried out the idea of digging up the bodies of young girls to satisfy his passions with, and whose case has been recorded by Belletrud and Mercier, said: "I could find no young girl who would agree to yield to my desires; that is why I have done this. I should have preferred to have relations with living persons. I found it quite natural to do what I did: I saw no harm in it, and I did not think that any one else could. As living women felt nothing but repulsion for me, it was quite natural I should turn to the dead, who have never repulsed me. I used to say tender things to them like 'my beautiful, my love, I love you.'" (Belletrud and Mercier "Perversion de l'Instinct Genésique," Annales d'Hygiène Publique, June, 1903.) But when so highly abnormal an act is felt as natural we are dealing with a person who is congenitally defective so far as the finer developments of intelligence are concerned. It was so in this case of necrophily; he was the son of a weak-minded woman of unrestrainable sexual inclinations, and was himself somewhat feeble-minded; he was also, it is instructive to observe, anosmic.

But it is by no means only their dulled sensibility or the absence of women, which accounts for the frequency of bestiality among peasants. A highly important factor is their constant familiarity with animals. The peasant lives with animals, tends them, learns to know all their individual characters; he understands them far better than he understands men and women; they are his constant companions, his friends. He knows, moreover, the details of their sexual lives, he witnesses the often highly impressive spectacle of their coupling. It is scarcely surprising that peasants should sometimes regard animals as being not only as near to them as their fellow human beings, but even nearer.

The significance of the factor of familiarity is indicated by the great frequency of bestiality among shepherds, goatherds, and others whose occupation is exclusively the care of animals. Mirabeau, in the eighteenth century, stated, on the evidence of Basque priests, that all the shepherds in the Pyrenees practice bestiality. It is apparently much the same in Italy.[[49]] In South Italy and Sicily, especially, bestiality among goatherds and peasants is said to be almost a national custom.[[50]] In the extreme north of Europe, it is reported, the reindeer, in this respect, takes the place of the goat.

The importance of the same factor is also shown by the fact that when among women in civilization animal perversions appear, the animal is nearly always a pet dog. Usually in these cases the animal is taught to give gratification by cunnilinctus. In some cases, however, there is really sexual intercourse between the animal and the woman.

Moll mentions that in a case of cunnilinctus by a dog in Germany there was a difficulty as to whether the matter should be considered an unnatural offence or simply an offence against decency; the lower court considered it in the former light, while the higher court took the more merciful view. (Moll, Untersuchungen über die Libido Sexualis, bd. i, p. 697.) In a case reported by Pfaff and mentioned by Moll, a country girl was accused of having sexual intercourse with a large dog. On examination Pfaff found in the girl's thick pubic hair a loose hair which under the microscope proved to belong to the dog. (Loc. cit., p. 698.) In such a case it must be noted that while this evidence may be held to show sexual contact with the dog, it scarcely suffices to show sexual intercourse. This has, however, undoubtedly occurred from time to time, even more or less openly. Bloch (Op. cit., pp. 277 and 282) remarks that this is not an infrequent exhibition given by prostitutes in certain brothels. Maschka has referred to such an exhibition between a woman and a bull-dog, which was given to select circles in Paris. Rosse refers to a case in which a young unmarried woman in Washington was surprised during intercourse with a large English mastiff, who in his efforts to get loose caused such severe injuries that the woman died from hæmorrhage in about an hour. Rosse also mentions that some years ago a performance of this kind between a prostitute and a Newfoundland dog could be witnessed in San Francisco by paying a small sum; the woman declared that a woman who had once copulated with a dog would ever afterwards prefer this animal to a man. Rosse adds that he was acquainted with a similar performance between a woman and a donkey, which used to take place in Europe (Irving Rosse, "Sexual Hypochondriasis and Perversion of the Genesic Instinct," Virginia Medical Monthly, October, 1892, p. 379). Juvenal mentions such relations between the donkey and woman (vi, 332). Krauss (quoted by Bloch, Beiträge zur Ætiologie der Psychopathia Sexualis, Teil II, p. 276) states that in Bosnia women sometimes carry on these practices with dogs and also—as he would not have believed had he not on one occasion observed it—with cats. "It seems to me," writes Dr. Kiernan, of Chicago, (private letter) "that what Rosse says of the animal exhibitions in San Francisco is true of all great cities. The animal employed in such exhibitions here has usually been a donkey, and in one instance death occurred from the animal trampling the girl partner. The practice described occurs in country regions quite frequently. Thus in a case reported in the suburbs of Omaha, Nebraska, a sixteen-year-old boy engaged in rectal coitus with a large dog. In attempting to extricate his swollen penis from the boy's rectum the dog tore through the sphincter ani an inch into the gluteus muscles. (Omaha Clinic, March, 1893.) In a Missouri case, which I verified, a smart, pretty, well-educated country girl was found with a profuse offensive vaginal discharge which had been present for about a week, coming on suddenly. After washing the external genitals and opening the labia three rents were discovered, one through the fourchette and two through the left nymphæ. The vagina was excessively congested and covered with points bleeding on the slightest irritation. The patient confessed that one day while playing with the genitals of a large dog she became excited and thought she would have slight coitus. After the dog had made an entrance she was unable to free herself from him, as he clasped her so firmly with his fore legs. The penis became so swollen that the dog could not free himself, although for more than an hour she made persistent efforts to do so. (Medical Standard, June, 1903, p. 184). In an Indiana case, concerning which I was consulted, the girl was a hebephreniac who had resorted to this procedure with a Newfoundland dog at the instance of another girl, seemingly normal as regards mentality, and had been badly injured; a discharge resulted which resembled gonorrhœa, but contained no gonococci. These cases are probably more frequent than is usually assumed."
