(M25) Nor are such customs and beliefs confined to the Christian peoples of Europe; they are shared also by the Mohammedan peoples of Morocco. There, too, on Midsummer Day all water is thought to be endowed with such marvellous virtue that it not only heals but prevents sickness for the rest of the year; hence men, women, and children bathe in the sea, in rivers, or in their houses at that time for the sake of their health. In Fez and other places on this day people pour or squirt water over each other in the streets or from the house-tops, so that the streets become almost as muddy as after a fall of rain. More than that, in the Andjra they bathe their animals also; horses, mules, donkeys, cattle, sheep, and goats, all must participate in the miraculous benefits of midsummer water.(80) The rite forms part of that old heathen celebration of Midsummer which appears to have been common to the peoples on both sides of the Mediterranean;(81) and as the aim of bathing in the midsummer water is undoubtedly purification, it is reasonable to assign the same motive for the custom of leaping over the midsummer bonfire. On the other hand some people in Morocco, like some people in Europe, think that water on Midsummer Day is unclean or dangerous. A Berber told Dr. Westermarck that water is haunted on Midsummer Day, and that people therefore avoid bathing in it and keep animals from drinking of it. And among the Beni Ahsen persons who swim in the river on that day are careful, before plunging into the water, to throw burning straw into it as an offering, in order that the spirits may not harm them.(82) The parallelism between the rites of water and fire at this season is certainly in favour of interpreting both in the same way;(83) and the traces of human sacrifice which we have detected in the rite of water may therefore be allowed to strengthen the inference of a similar sacrifice in the rite of fire.
