That there are annual seasonal changes in the human organism, especially connected with the sexual function, is a statement that has been made by physiologists and others from time to time, and the statement has even reached the poets, who have frequently declared that spring is the season of love.
Thus, sixty years ago, Laycock, an acute pioneer in the investigation of the working of the human organism, brought together (in a chapter on "The Periodic Movements in the Reproductive Organs of Woman," in his _Nervous Diseases of Women_, 1840, pp. 61-70) much interesting evidence to show that the system undergoes changes about the vernal and autumnal equinoxes, and that these changes are largely sexual.
Edward Smith, also a notable pioneer in this field of human periodicity, and, indeed, the first to make definite observations on a number of points bearing on it, sums up, in his remarkable book, _Health and Disease as Influenced by Daily, Seasonal, and Other Cyclical Changes in the Human System_ (1861), to the effect that season is a more powerful influence on the system than temperature or atmospheric pressure; "in the early and middle parts of spring every function of the body is in its highest degree of efficiency," while autumn is "essentially a period of change from the minimum toward the maximum of vital conditions." He found that in April and May most carbonic acid is evolved, there being then a progressive diminution to September, and then a progressive increase; the respiratory rate also fell from a maximum in April to a minimum maintained at exactly the same level throughout August, September, October, and November; spring was found to be the season of maximum, autumn of minimum, muscular power; sensibility to tactile and temperature impressions was also greater in spring.
Kulischer, studying the sexual customs of various human races, concluded that in primitive times, only at two special seasons--at spring and in harvest-time--did pairing take place; and that, when pairing ceased to be strictly confined to these periods, its symbolical representation was still so confined, even among the civilized nations of Europe. He further argued that the physiological impulse was only felt at these periods. (Kulischer, "Die geschlechtliche Zuchtwahl bei den Menschen in der Urzeit," _Zeitschrift für Ethnologie_, 1876, pp. 152 and 157.) Cohnstein ("Ueber Prädilectionszeiten bei Schwangerschaft," _Archiv für Gynäkologie_, 1879) also suggested that women sometimes only conceive at certain periods of the year.
Wiltshire, who made various interesting observations regarding the physiology of menstruation, wrote: "Many years ago, I concluded that every women had a law peculiar to herself, which governed the times of her bringing forth (and conceiving); that she was more prone to bring forth at certain epochs than at others; and subsequent researches have established the accuracy of the forecast." He further stated his belief in a "primordial seasonal aptitude for procreation, the impress of which still remains, and, to some extent, governs the breeding-times of humanity." (A. Wiltshire, "Lectures on the Comparative Physiology of Menstruation," _British Medical Journal_, March, 1883, pp. 502, etc.)
Westermarck, in a chapter of his _History of Human Marriage_, dealing with the question of "A Human Pairing Season in Primitive Times," brings forward evidence showing that spring, or, rather, early summer, is the time for increase of the sexual instinct, and argues that this is a survival of an ancient pairing season; spring, he points out, is a season of want, rather than abundance, for a frugivorous species, but when men took to herbs, roots, and animal food, spring became a time of abundance, and suitable for the birth of children. He thus considers that in man, as in lower animals, the times of conception are governed by the times most suitable for birth.
Rosenstadt, as we shall see later, also believes that men to-day have inherited a physiological custom of procreating at a certain epoch, and he thus accounts for the seasonal changes in the birthrate.
Heape, who also believes that "at one period of its existence the human species had a special breeding season," follows Wiltshire in suggesting that "there is some reason to believe that the human female is not always in a condition to breed." (W. Heape, "Menstruation and Ovulation of _Macacus rhesus_," _Philosophical Transactions_, 1897; id. "The Sexual Season of Mammals," _Quarterly Journal Microscopical Science_, 1900.)
Except, however, in one important respect, with which we shall presently have to deal, few attempts have been made to demonstrate any annual organic sexual rhythm. The supposition of such annual cycle is usually little more than a deduction from the existence of the well-marked seasonal sexual rhythm in animals. Most of the higher animals breed only once or twice a year, and at such a period that the young are born when food is most plentiful. At other periods the female is incapable of breeding, and without sexual desires, while the male is either in the same condition or in a condition of latent sexuality. Under the influence of domestication, animals tend to lose the strict periodicity of the wild condition, and become apt for breeding at more frequent intervals. Thus among dogs in the wild state the bitch only experiences heat once a year, in the spring. Among domesticated dogs, there is not only the spring period of heat, early in the year, but also an autumn period, about six months later; the primitive period, however, remains the most important one, and the best litters of pups are said to be produced in the spring. The mare is in season in spring and summer; sheep take the ram in autumn.[128] Many of the menstruating monkeys also, whether or not sexual desire is present throughout the year, only conceive in spring and in autumn. Almost any time of the year may be an animal's pairing season, this season being apparently in part determined by the economic conditions which will prevail at birth. While it is essential that animals should be born during the season of greatest abundance, it is equally essential that pairing, which involves great expenditure of energy, should also take place at a season of maximum physical vigor.
As an example of the sexual history of an animal through the year, I may quote the following description, by Dr. A.W. Johnstone, of the habits of the American deer: "Our common American deer, in winter-time, is half-starved for lack of vegetation in the woods; the low temperature, snow, and ice, make his conditions of life harder for lack of the proper amount of food, whereby he becomes an easier prey to carnivorous animals. He has difficulty even in preserving life. In spring he sheds his winter coat, and is provided with a suit of lighter hair, and while this is going on the male grows antlers for defence. The female about this time is far along in pregnancy, and when the antlers are fully grown she drops the fawn. When the fawns are dropped vegetation is plentiful and lactation sets in. During this time the male is kept fully employed in getting food and guarding his more or less helpless family. As the season advances the vegetation increases and the fawn begins to eat grass. When the summer heat commences the little streams begin to dry up, and the animal once more has difficulty in supporting life because of the enervating heat, the effect of drought on the vegetation, and the distance which has to be traveled to get water; therefore, fully ten months in each year the deer has all he can do to live without extra exertion incident to rutting. Soon after the autumn rains commence vegetation becomes more luxurious, the antlers of the male and new suits of hair for both are fully grown, heat of the summer is gone, food and drink are plentiful everywhere, the fawns are weaned, and both sexes are in the very finest condition. Then, and then only, in the whole year, comes the rut, which, to them as to most other animals, means an unwonted amount of physical exercise besides the everyday runs for life from their natural enemies, and an unusual amount of energy is used up. If a doe dislikes the attention of a special buck, miles of racing result. If jealous males meet, furious battles take place. The strain on both sexes could not possibly be endured at any other season of the year. With approach of cold weather, climatic deprivations and winter dangers commence and rut closes. In all wild animals, rut occurs only when the climatic and other conditions favor the highest physical development. This law holds good in all wild birds, for it is then only that they can stand the strain incident to love-making. The common American crow is a very good study. In the winter he travels around the ricefields of the South, leading a tramp's existence in a country foreign to him, and to which he goes only to escape the rigors of the northern climate. For several weeks in the spring he goes about the fields, gathering up the worms and grubs. After his long flight from the South he experiences several weeks of an almost ideal existence, his food is plentiful, he becomes strong and hearty, and then he turns to thoughts of love. In the pairing season he does more work than at any other time in the year: fantastic dances, racing and chasing after the females, and savage fights with rivals. He endures more than would be possible in his ordinary physical state. Then come the care of the young and the long flights for water and food during the drought of the summer. After the molt, autumn finds him once more in flock, and with the first frosts he is off again to the South. In the wild state, rut is the capstone of perfect physical condition." (A.W. Johnstone, "The Relation of Menstruation to the other Reproductive Functions," _American Journal of Obstetrics_, vol. xxxii, 1895.)
Wiltshire ("Lectures on the Comparative Physiology of Menstruation," _British Medical Journal_, March, 1888) and Westermarck (_History of Human Marriage_, Chapter II) enumerate the pairing season of a number of different animals.
With regard to the breeding seasons of monkeys, little seems to be positively known. Heape made special inquiries with reference to the two species whose sexual life he investigated. He was informed that _Semnopithecus entellus_ breeds twice a year, in April and in October. He accepts Aitcheson's statement that the _Macacus rhesus_, in Simla, copulates in October, and adds that in the very different climate of the plains it appears to copulate in May. He concludes that the breeding season varies greatly in dependence on climate, but believes that the breeding season is always preserved, and that it affects the sexual aptitude of the male. He could not make his monkeys copulate during February or March, but is unable to say whether or not sexual intercourse is generally admitted outside the breeding season. He quotes the observation of Breschet that monkeys copulate during pregnancy.
In primitive human races we very frequently trace precisely the same influence of the seasonal impulse as may be witnessed in the higher animals, although among human races it does not always result that the children are born at the time of the greatest plenty, and on account of the development of human skill such a result is not necessary. Thus Dr. Cook found among the Eskimo that during the long winter nights the secretions are diminished, muscular power is weak, and the passions are depressed. Soon after the sun appears a kind of rut affects the young population. They tremble with the intensity of sexual passion, and for several weeks much of the time is taken up with courtship and love. Hence, the majority of the children are born nine months later, when the four months of perpetual night are beginning. A marked seasonal periodicity of this kind is not confined to the Arctic regions. We may also find it in the tropics. In Cambodia, Mondière has found that twice a year, in April and September, men seem to experience a "veritable rut," and will sometimes even kill women who resist them.[129] These two periods, spring and autumn--the season for greeting the appearance of life and the season for reveling in its final fruition--seem to be everywhere throughout the world the most usual seasons for erotic festivals. In classical Greece and Rome, in India, among the Indians of North and South America, spring is the most usual season, while in Africa the yam harvest of autumn is the season chiefly selected. There are, of course, numerous exceptions to this rule, and it is common to find both seasons observed. Taking, indeed, a broad view of festivals throughout the world, we may say that there are four seasons when they are held: the winter solstice, when the days begin to lengthen and primitive man rejoices in the lengthening and seeks to assist it;[130] the vernal equinox, the period of germination and the return of life; the summer solstice, when the sun reaches its height; and autumn, the period of fruition, of thankfulness, and of repose. But it is rarely that we find a people seriously celebrating more than two of these festival seasons.
In Australia, according to Müller as quoted by Ploss and Bartels, marriage and conception take place during the warm season, when there is greatest abundance of food, and to some extent is even confined to that period. Oldfield and others state that the Australian erotic festivals take place only in spring. Among some tribes, Müller adds, such as the Watschandis, conception is inaugurated by a festival called _kaaro_, which takes place in the warm season at the first new moon after the yams are ripe. The leading feature of this festival is a moonlight dance, representing the sexual act symbolically. With their spears, regarded as the symbols of the male organ, the men attack bushes, which represent the female organs. They thus work themselves up to a state of extreme sexual excitement.[131] Among the Papuans of New Guinea, also, according to Miklucho-Macleay, conceptions chiefly occur at the end of harvest, and Guise describes the great annual festival of the year which takes place at the time of the yam and banana harvest, when the girls undergo a ceremony of initiation and marriages are effected.[132] In Central Africa, says Sir H.H. Johnston, in his _Central Africa_, sexual orgies are seriously entered into at certain seasons of the year, but he neglects to mention what these seasons are. The people of New Britain, according to Weisser (as quoted by Ploss and Bartels), carefully guard their young girls from the young men. At certain times, however, a loud trumpet is blown in the evening, and the girls are then allowed to go away into the bush to mix freely with the young men. In ancient Peru (according to an account derived from a pastoral letter of Archbishop Villagomez of Lima), in December, when the fruit of the _paltay_ is ripe, a festival was held, preceded by a five days' fast. During the festival, which lasted six days and six nights, men and women met together in a state of complete nudity at a certain spot among the gardens, and all raced toward a certain hill. Every man who caught up with a woman in the race was bound at once to have intercourse with her.
Very instructive, from our present point of view, is the account given by Dalton, of the festivals of the various Bengal races. Thus the Hos (a Kolarian tribe), of Bengal, are a purely agricultural people, and the chief festival of the year with them is the _mágh parah_. It is held in the month of January, "when the granaries are full of grain, and the people, to use their own expression, full of devilry." It is the festival of the harvest-home, the termination of the year's toil, and is always held at full moon. The festival is a _saturnalia_, when all rules of duty and decorum are forgotten, and the utmost liberty is allowed to women and girls, who become like bacchantes. The people believe that at this time both men and women become overcharged with vitality, and that a safety valve is absolutely necessary. The festival begins with a religious sacrifice made by the village priest or elders, and with prayers for the departed and for the vouchsafing of seasonable rain and good crops. The religious ceremonies over, the people give themselves up to feasting and to drinking the home-made beer, the preparation of which from fermented rice is one of a girl's chief accomplishments. "The Ho population," wrote Dalton, "are at other seasons quiet and reserved in manner, and in their demeanor toward women gentle and decorous; even in their flirtations they never transcend the bounds of decency. The girls, though full of spirits and somewhat saucy, have innate notions of propriety that make them modest in demeanor, though devoid of all prudery, and of the obscene abuse, so frequently heard from the lips of common women in Bengal, they appear to have no knowledge. They are delicately sensitive under harsh language of any kind, and never use it to others; and since their adoption of clothing they are careful to drape themselves decently, as well as gracefully; but they throw all this aside during the _mágh_ feast. Their nature appears to undergo a temporary change. Sons and daughters revile their parents in gross language, and parents their children; men and women become almost like animals in the indulgence of their amorous propensities. They enact all that was ever portrayed by prurient artists in a bacchanalian festival or pandean orgy; and as the light of the sun they adore, and the presence of numerous spectators, seems to be no restraint on their indulgence, it cannot be expected that chastity is preserved when the shades of night fall on such a scene of licentiousness and debauchery." While, however, thus representing the festival as a mere debauch, Dalton adds that relationships formed at this time generally end in marriage. There is also a flower festival in April and May, of religious nature, but the dances at this festival are quieter in character.[133] In Burmah the great festival of the year is the full moon of October, following the Buddhist Lent season (which is also the wet season), during which there is no sexual intercourse. The other great festival is the New Year in March.[134] In classical times the great festivals were held at the same time as in northern and modern Europe. The _brumalia_ took place in midwinter, when the days were shortest, and the _rosalia_, according to early custom in May or June, and at a later time about Easter. After the establishment of Christianity the Church made constant efforts to suppress this latter festival, and it was referred to by an eighth century council as "a wicked and reprehensible holiday-making." These festivals appear to be intimately associated with Dionysus worship, and the flower-festival of Dionysus, as well as the Roman Liberales in honor of Bacchus, was celebrated in March with worship of Priapus. The festivals of the Delian Apollo and of Artemis, both took place during the first week in May and the Roman Bacchanales in October.[135] The mediæval Feast of Fools was to a large extent a seasonal orgy licensed by the Church. It may be traced directly back through the barbatories of the lower empire to the Roman _saturnalia_, and at Sens, the ancient ecclesiastical metropolis of France, it was held at about the same time as the _saturnalia_, on the Feast of the Circumcision, i.e., New Year's Day. It was not, however, always held at this time; thus at Evreux it took place on the 1st of May.[136] The Easter bonfires of northern-central Europe, the Midsummer (St. John's Eve) fires of southern-central Europe, still bear witness to the ancient festivals.[137] There is certainly a connection between these bonfires and erotic festivals; it is noteworthy that they occur chiefly at the period of spring and early summer, which, on other grounds, is widely regarded as the time for the increase of the sexual instinct, while the less frequent period for the bonfires is that of the minor sexual climax. Mannhardt was perhaps the first to show how intimately these spring and early summer festivals--held with bonfires and dances and the music of violin--have been associated with love-making and the choice of a mate.[138] In spring, the first Monday in Lent (Quadrigesima) and Easter Eve were frequent days for such bonfires. In May, among the Franks of the Main, the unmarried women, naked and adorned with flowers, danced on the Blocksberg before the men, as described by Herbels in the tenth century.[139] In the central highlands of Scotland the Beltane fires were kindled on the 1st of May. Bonfires sometimes took place on Halloween (October 31st) and Christmas. But the great season all over Europe for these bonfires, then often held with erotic ceremonial, is the summer solstice, the 23d of June, the eve of Midsummer, or St. John's Day.[140] The Bohemians and other Slavonic races formerly had meetings with sexual license. This was so up to the beginning of the sixteenth century on the banks of rivers near Novgorod. The meetings took place, as a rule, the day before the Festival of John the Baptist, which, in pagan times, was that of a divinity known by the name of Jarilo (equivalent to Priapus). Half a century later, a new ecclesiastical code sought to abolish every vestige of the early festivals held on Christmas Day, on the Day of the Baptism, of Our Lord, and on John the Baptist's Day. A general feature of all these festivals (says Kowalewsky) was the prevalence of the promiscuous intercourse of the sexes. Among the Ehstonians, at the end of the eighteenth century, thousands of persons would gather around an old ruined church (in the Fellinschen) on the Eve of St. John, light a bonfire, and throw sacrificial gifts into it. Sterile women danced naked among the ruins; much eating and drinking went on, while the young men and maidens disappeared into the woods to do what they would. Festivals of this character still take place at the end of June in some districts. Young unmarried couples jump barefoot over large fires, usually near rivers or ponds. Licentiousness is rare.[141] But in many parts of Russia the peasants still attach little value to virginity, and even prefer women who have been mothers. The population of the Grisons in the sixteenth century held regular meetings not less licentious than those of the Cossacks. These were abolished by law. Kowalewsky regards all such customs as a survival of early forms of promiscuity.[142] Frazer (_Golden Bough_, 2d ed., 1900, vol. iii, pp. 236-350) fully describes and discusses the dances, bonfires and festivals of spring and summer, of Halloween (October 31), and Christmas. He also explains the sexual character of these festivals. "There are clear indications," he observes (p. 305), "that even human fecundity is supposed to be promoted by the genial heat of the fires. It is an Irish belief that a girl who jumps thrice over the midsummer bonfire will soon marry and become the mother of many children; and in various parts of France they think that if a girl dances round nine fires she will be sure to marry within a year. On the other hand, in Lechrain, people say that if a young man and woman, leaping over the midsummer fire together, escape unsmirched, the young woman will not become a mother within twelve months--the flames have not touched and fertilized her. The rule observed in some parts of France and Belgium, that the bonfires on the first Sunday in Lent should be kindled by the person who was last married, seems to belong to the same class of ideas, whether it be that such a person is supposed to receive from, or impart to, the fire a generative and fertilizing influence. The common practice of lovers leaping over the fires hand-in-hand may very well have originated in a notion that thereby their marriage would be more likely to be blessed with offspring. And the scenes of profligacy which appear to have marked the midsummer celebration among the Ehstonians, as they once marked the celebration of May Day among ourselves, may have sprung, not from the mere license of holiday-makers, but from a crude notion that such orgies were justified, if not required, by some mysterious bond which linked the life of man, to the courses of the heavens at the turning-point of the year."
As regards these primitive festivals, although the evidence is scattered and sometimes obscure, certain main conclusions clearly emerge. In early Europe there were, according to Grimm, only two seasons, sometimes regarded as spring and winter, sometimes as spring and autumn, and for mythical purposes these seasons were alone available.[143] The appearance of each of these two seasons was inaugurated by festivals which were religious and often erotic in character. The Slavonic year began in March, at which time there was formerly, it is believed, a great festival, not only in Slavonic but also in Teutonic countries. In Northern Germany there were Easter bonfires always associated with mountains or hills. The Celtic bonfires were held at the beginning of May, while the Teutonic May-day, or _Walpurgisnacht_, is a very ancient sacred festival, associated with erotic ceremonial, and regarded by Grimm as having a common origin with the Roman _floralia_ and the Greek _dionysia_. Thus, in Europe, Grimm concludes: "there are four different ways of welcoming summer. In Sweden and Gothland a battle of winter and summer, a triumphal entry of the latter. In Schonen, Denmark, Lower Saxony, and England, simply May-riding, or fetching of the May-wagon. On the Rhine merely a battle of winter and summer, without immersion, without the pomp of an entry. In Franconia, Thuringia, Meissen, Silesia, and Bohemia only the carrying out of wintry death; no battle, no formal introduction of summer. Of these festivals the first and second fall in May, the third and fourth in March. In the first two, the whole population take part with unabated enthusiasm; in the last two only the lower poorer class...Everything goes to prove that the approach of summer was to our forefathers a holy tide, welcomed by sacrifice, feast, and dance, and largely governing and brightening the people's life."[144] The early spring festival of March, the festival of Ostara, the goddess of spring, has become identified with the Christian festival of Resurrection (just as the summer solstice festival has been placed beneath the patronage of St. John the Baptist); but there has been only an amalgamation of closely-allied rites, for the Christian festival also may be traced back to a similar origin. Among the early Arabians the great _ragab_ feast, identified by Ewald and Robertson Smith with the Jewish _paschal_ feast, fell in the spring or early summer, when the camels and other domestic animals brought forth their young and the shepherds offered their sacrifices.[145] Babylonia, the supreme early centre of religious and cosmological culture, presents a more decisive example of the sex festival. The festival of Tammuz is precisely analogous to the European festival of St. John's Day. Tammuz was the solar god of spring vegetation, and closely associated with Ishtar, also an agricultural deity of fertility. The Tammuz festival was, in the earliest times, held toward the summer solstice, at the time of the first wheat and barley harvest. In Babylonia, as in primitive Europe, there were only two seasons; the festival of Tammuz, coming at the end of winter and the beginning of summer, was a fast followed by a feast, a time of mourning for winter, of rejoicing for summer. It is part of the primitive function of sacred ritual to be symbolical of natural processes, a mysterious representation of natural processes with the object of bringing them about.[146] The Tammuz festival was an appeal to the powers of Nature to exhibit their generative functions; its erotic character is indicated not only by the well-known fact that the priestesses of Ishtar (the Kadishtu, or "holy ones") were prostitutes, but by the statements in Babylonian legends concerning the state of the earth during Ishtar's winter absence,
