(M126) In the Shetland Islands the Yule or Christmas holidays begin, or used to begin, seven days before Christmas and last till Antinmas, that is, the twenty-fourth day after Christmas. In the Shetland parlance these holidays are known as “the Yules.” On the first night, called Tul-ya’s e’en, seven days before Christmas, certain mischievous elves, whom the Shetlanders name Trows, “received permission to leave their homes in the heart of the earth and dwell, if it so pleased them, above ground. There seemed to have been no doubt that those creatures preferred disporting themselves among the dwellings of men to residing in their own subterranean abodes, for they availed themselves of every permission given, and created no little disturbance among the mortals whom they visited. One of the most important of all Yule-tide observances was the ‘saining’ required to guard life or property from the Trows. If the proper observances were omitted, the ‘grey-folk’ were sure to take advantage of the opportunity.”(420) On the last day of the holidays, the twenty-fourth day after Christmas, which in Shetland goes by the name of Up-helly-a’, Uphellia, or Uphaliday, “the doors were all opened, and a great deal of pantomimic chasing and driving and dispersing of unseen creatures took place. Many pious ejaculations were uttered, and iron was ostentatiously displayed, ‘for Trows can never abide the sight o’ iron.’ The Bible was read and quoted. People moved about in groups or couples, never singly, and infants were carefully guarded as well as sained by vigilant and learned ‘wise women.’ Alas, the poor Trows! their time of frolic and liberty was ended, and on Twenty-fourth night they retired to their gloomy abodes beneath the sod, seldom finding opportunity to reappear again, and never with the same licence, until the Yules returned. All that pantomime, all that invoking of holier Powers, were but methods of ‘speeding the parting guest,’ and mortals were rejoicing that the unbidden, unwelcome grey-folk must depart. When day dawned after Twenty-fourth night the Trows had vanished and the Yules were ended.”(421) Of late years Up-helly-a’ has been celebrated in Lerwick with pompous and elaborate masquerades. The chief event of the evening is a torch-light procession of maskers or “guizers,” as they are called, who escort the model of a Norse galley through the streets, and finally set it on fire by throwing their torches into it. But in this form the celebration seems to date only from the latter part of the nineteenth century; in former times an old boat filled with tar and ignited was dragged about and blazing tar-barrels were drawn or kicked through the streets.(422) The fire, however procured, was probably in origin intended to chase away the lingering Trows from the town at the end of the holidays.
