A farmer’s son returning from Beddgelert fair, seeing some fairies dancing and capering, sat down to watch them, and very soon fell asleep. Whether or not the sight of a sleeping mortal was to much of a temptation to them to indulge in a little mischief, they at any rate they at any rate proceeded to tie him down and that so firmly ‘that he could not have stirred; then they covered him with a gossamer sheet, so that nobody could see him.’ Search was made by his family for him but in vain. After a day and a night like that he was released and for some time wandered about not knowing where he was. At cock-crow, however, he came to himself and discovered that he was only a quarter of a mile from home. These were said to be ‘mischevious and wanton kind of fairies who dwelt in marshy and rushy places, or among the fern and the heather.’ D. Parry-Jones, Welsh Legends and Fairy Lore, 26
