Again, women after childbirth and their offspring are more or less tabooed all the world over; hence in Corea the rays of the sun are rigidly excluded from both mother and child for a period of twenty-one or a hundred days, according to their rank, after the birth has taken place.[57] Among some of the tribes on the north-west coast of New Guinea a woman may not leave the house for months after childbirth. When she does go out, she must cover her head with a hood or mat; for if the sun were to shine upon her, it is thought that one of her male relations would die.[58] Again, mourners are everywhere taboo; accordingly in mourning the Ainos of Japan wear peculiar caps in order that the sun may not shine upon their heads.[59] During a solemn fast of three days the Indians of Costa Rica eat no salt, speak as little as possible, light no fires, and stay strictly indoors, or if they go out during the day they carefully cover themselves from the light of the sun, believing that exposure to the sun's rays would turn them black.[60] On Yule Night it has been customary in parts of Sweden from time immemorial to go on pilgrimage, whereby people learn many secret things and know what is to happen in the coming year. As a preparation for this pilgrimage, "some secrete themselves for three days previously in a dark cellar, so as to be shut out altogether from the light of heaven. Others retire at an early hour of the preceding morning to some out-of-the-way place, such as a hay-loft, where they bury themselves in the hay, that they may neither see nor hear any living creature; and here they remain, in silence and fasting, until after sundown; whilst there are those who think it sufficient if they rigidly abstain from food on the day before commencing their wanderings. During this period of probation a man ought not to see fire, but should this have happened, he must strike a light with flint and steel, whereby the evil that would otherwise have ensued will be obviated."[61] During the sixteen days that a Pima Indian is undergoing purification for killing an Apache he may not see a blazing fire.[62] [The story of Prince Sunless.] Acarnanian peasants tell of a handsome prince called Sunless, who would die if he saw the sun. So he lived in an underground palace on the site of the ancient Oeniadae, but at night he came forth and crossed the river to visit a famous enchantress who dwelt in a castle on the further bank. She was loth to part with him every night long before the sun was up, and as he turned a deaf ear to all her entreaties to linger, she hit upon the device of cutting the throats of all the cocks in the neighbourhood. So the prince, whose ear had learned to expect the shrill clarion of the birds as the signal of the growing light, tarried too long, and hardly had he reached the ford when the sun rose over the Aetolian mountains, and its fatal beams fell on him before he could regain his dark abode.[63] Notes:
