A question of historical psychology which, so far as I know, has never been fully investigated is the influence of menstruation in constituting the emotional atmosphere through which men habitually view women.[353] I do not purpose to deal fully with this question, because it is one which may be more properly dealt with at length by the student of culture and by the historian, rather than from the standpoint of empirical psychology. It is, moreover, a question full of complexities in regard to which it is impossible to speak with certainty. But we here strike on a factor of such importance, such neglected importance, for the proper understanding of the sexual relations of men and women, that it cannot be wholly ignored.
Among the negroes of Surinam a woman must live in solitude during the time of her period; it is dangerous for any man or woman to approach her, and when she sees a person coming near she cries out anxiously: "Mi kay! Mi kay!"—I am unclean! I am unclean! Throughout the world we find traces of the custom of which this is a typical example, but we must not too hastily assume that this custom is evidence of the inferior position occupied by semi-civilized women. It is necessary to take a broad view, not only of the beliefs of semi-civilized man regarding menstruation, but of his general beliefs regarding the supernatural forces of the world.
There is no fragment of folk-lore so familiar to the European world as that which connects woman with the serpent. It is, indeed, one of the foundation stones of Christian theology.[354] Yet there is no fragment of folk-lore which remains more obscure. How has it happened that in all parts of the world the snake or his congeners, the lizard and the crocodile, have been credited with some design, sinister or erotic, on women?
Of the wide prevalence of the belief there can be no doubt. Among the Port Lincoln tribe of South Australia a lizard is said to have divided man from woman.[355] Among the Chiriguanos of Bolivia, on the appearance of menstruation, old women ran about with sticks to hunt the snake that had wounded the girl. Frazer, who quotes this example from the "Lettres édifiantes et curieuses," also refers to a modern Greek folk-tale, according to which a princess at puberty must not let the sun shine upon her, or she would be turned into a lizard.[356] The lizard was a sexual symbol among the Mexicans. In some parts of Brazil at the onset of puberty a girl must not go into the woods for fear of the amorous attacks of snakes, and so it is also among the Macusi Indians of British Guiana, according to Schomburgk. Among the Basutos of South Africa the young girls must dance around the clay image of a snake. In Polynesian mythology the lizard is a very sacred animal, and legends represent women as often giving birth to lizards.[357] At a widely remote spot, in Bengal, if you dream of a snake a child will be born to you, reports Sarat Chandra Mitra.[358] In the Berlin Museum für Volkerkunde there is a carved wooden figure from New Guinea of a woman into whose vulva a crocodile is inserting its snout, while the same museum contains another figure of a snake-like crocodile crawling out of a woman's vulva, and a third figure shows a small round snake with a small head, and closely resembling a penis, at the mouth of the vagina. All these figures are reproduced by Ploss and Bartels. Even in modern Europe the same ideas prevail. In Portugal, according to Reys, it is believed that during menstruation women are liable to be bitten by lizards, and to guard against this risk they wear drawers during the period. In Germany, again, it was believed, up to the eighteenth century at least, that the hair of a menstruating woman, if buried, would turn into a snake. It may be added that in various parts of the world virgin priestesses are dedicated to a snake-god and are married to the god.[359] At Rome, it is interesting to note, the serpent was the symbol of fecundation, and as such often figures at Pompeii as the genius patrisfamilias, the generative power of the family.[360] In Rabbinical tradition, also, the serpent is the symbol of sexual desire.
There can be no doubt that—as Ploss and Bartels, from whom some of these examples have been taken, point out—in widely different parts of the world menstruation is believed to have been originally caused by a snake, and that this conception is frequently associated with an erotic and mystic idea.[361] How the connection arose Ploss and Bartels are unable to say. It can only be suggested that its shape and appearance, as well as its venomous nature, may have contributed to the mystery everywhere associated with the snake—a mystery itself fortified by the association with women—to build up this world-wide belief regarding the origin of menstruation.
This primitive theory of the origin of menstruation probably brings before us in its earliest shape the special and intimate bond which has ever been held to connect women, by virtue of the menstrual process, with the natural or supernatural powers of the world. Everywhere menstruating women are supposed to be possessed by spirits and charged with mysterious forces. It is at this point that a serious misconception, due to ignorance of primitive religious ideas, has constantly intruded. It is stated that the menstruating woman is "unclean" and possessed by an evil spirit. As a matter of fact, however, the savage rarely discriminates between bad and good spirits. Every spirit may have either a beneficial or malignant influence. An interesting instance of this is given in Colenso's Maori Lexicon as illustrated by the meaning of the Maori word atua.
The importance of recognizing the special sense in which the word "unclean" is used in this connection was clearly pointed out by Robertson Smith in the case of the Semites. "The Hebrew word tame (unclean)," he remarked, "is not the ordinary word for things physically foul; it is a ritual term, and corresponds exactly to the idea of taboo. The ideas 'unclean' and 'holy' seem to us to stand in polar opposition to one another, but it was not so with the Semites. Among the later Jews the Holy Books 'defiled the hands' of the reader as contact with an impure thing did; among Lucian's Syrians the dove was so holy that he who touched it was unclean for a day; and the taboo attaching to the swine was explained by some, and beyond question correctly explained, in the same way. Among the heathen Semites,[362] therefore, unclean animals, which it was pollution to eat, were simply holy animals." Robertson Smith here made no reference to menstruation, but he exactly described the primitive attitude toward menstruation. Wellhausen, however, dealing with the early Arabians, expressly mentions that in pre-Islamic days, "clean" and "unclean" were used solely with reference to women in and out of the menstrual state. At a later date Frazer developed this aspect of the conception of taboo, and showed how it occurs among savage races generally. He pointed out that the conceptions of holiness and pollution not having yet been differentiated, women at childbirth and during menstruation are on the same level as divine kings, chiefs, and priests, and must observe the same rules of ceremonial purity. To seclude such persons from the rest of the world, so that the dreaded spiritual danger shall not spread, is the object of the taboo, which Frazer compares to "an electrical insulator to preserve the spiritual force with which these persons are charged from suffering or inflicting, harm by contact with the outer world." After describing the phenomena (especially the prohibition to touch the ground or see the sun) found among various races, Frazer concludes: "The object of secluding women at menstruation is to neutralize the dangerous influences which are supposed to emanate from them at such times. The general effect of these rules is to keep the girl suspended, so to say, between heaven and earth. Whether enveloped in her hammock and slung up to the roof, as in South America, or elevated above the ground in a dark and narrow cage, as in New Zealand, she may be considered to be out of the way of doing mischief, since, being shut off both from the earth and from the sun, she can poison neither of these great sources of life by her deadly contagion. The precautions thus taken to isolate or insulate the
