the offspring of such a union was fathered on the river-god.[536] The bath which a Greek bride and bridegroom regularly took before marriage appears to have been intended to bless their union with offspring through the fertilising influence of the water-nymphs.[537] Thus it would appear that in many parts of the world a custom has prevailed of sacrificing human beings to water-spirits, and that in not a few cases the ceremony has taken the form of making over a woman to the spirit to be his wife, in order either to pacify his fury or to give play to his generative powers. Where the water-spirit was regarded as female, young men might be presented to her for a similar purpose, and this may be the reason why the victims sacrificed to water-spirits are sometimes males. Among civilised peoples these customs survive for the most part only in popular tales, of which the legend of Perseus and Andromeda, with its mediaeval counterpart of St. George and the Dragon, is the most familiar example. But occasionally they appear to have left traces of themselves in ceremonies and pageants. Thus at Furth in Bavaria a [Sidenote: Midsummer custom of slaying the dragon at Furth in Bavaria.] drama called the Slaying of the Dragon used to be acted every year about Midsummer, on the Sunday after Corpus Christi Day. Crowds of spectators flocked from the neighbourhood to witness it. The scene of the performance was the public square. On a platform stood or sat a princess wearing a golden crown on her head, and as many silver ornaments on her body as could be borrowed for the purpose. She was attended by a maid of honour. Opposite her was stationed the dragon, a dreadful monster of painted canvas stretched on a wooden skeleton and moved by two men inside. From time to time the creature would rush with gaping jaws into the dense crowd of spectators, who retreated hastily, tumbling over each other in their anxiety to escape. Then a knight in armour, attended by his men-at-arms, rode forth and asked the princess what she did “on this hard stone,” and why she looked so sad. She told him that the dragon was coming to eat her up. On that the knight bade her be of good cheer, for that with his sword he would rid the country of the monster. With that he charged the dragon, thrusting his spear into its maw and taking care to stab a bladder of bullock’s blood which was there concealed. The gush of blood which followed was an indispensable part of the show, and if the knight missed his stroke he was unmercifully jeered and taunted by the crowd. Having despatched the monster with sword and pistol, the knight then hastened to the princess and told her that he had slain the dragon who had so long oppressed the town. In return she tied a wreath round his arm, and announced that her noble father and mother would soon come to give them half the kingdom. The men-at-arms then escorted the knight and the princess to the tavern, there to end the day with dance and revelry.
