When _Fjölnir_ assisted King Frodi in Denmark, he was given a loft-room as a sleeping apartment; in an adjoining loft-room the flooring had been removed, in order to fill the large mead-vat standing in the _undir-skemma_. During the night _Fjölnir_ went out, and as he had to return along the _svalir_ to his room, he made a mistake as to the door, and fell down into the mead-vat.[201] The beds (_hvila_, _rekkja_) were placed round the walls, inside the benches, and consisted of straw, the covering being the clothes worn in the daytime, and over the head a _feld_ (fur cloak) was placed. The buildings had windows, sometimes called light-holes, covered with a membrane, instead of glass, sufficiently large to enable a man to creep through them. The material used was the after-birth membrane, enclosing the fœtus of the cow, which was stretched over the light-hole. This when dried is almost as transparent as glass, and can, for a certain time, resist the rain. It is still in use in some out-of-the-way places in Iceland; in the Sagas it is called _Skjall_, and the window is called _Skja_. “Also if men sit in houses with _skjá_ (light-holes) in them, it is so light inside that all men indoors recognise each other” (Konungs Skuggsja, p. 47). There was no ceiling within the roof; the smoke from the open hearths on the floor, which covered the inside with soot, escaped through the _Ljori_, of which there was at least one, and which also admitted light.[202] “Olaf Tryggvason burnt the hall of the seid-man Eyvind Kelda who escaped through the _Ljóri_ (the light-hole in the roof)” (Olaf Trygg, c. 69). We find that turf was occasionally used as fuel. “Einar sailed westward to Shetland, and many men joined him. After that he went southward to the Orkneys, against Kalf Skurfa and Thorir (Treskegg). There a great battle was fought, and both the Vikings were slain. ‘He gave Treskegg to the Trölls; Torfeinar slew Skurfa: He conquered the islands.’ “After that he conquered the islands, and became a powerful chief. He was the first man to cut turf from the ground for fuel at Torfnes (Turfness) in Scotland, for fuel was scarce in the islands” (Flateyjarbók, vol. i., p. 223).
