The Scandinavian form of the "Greek" loom from the Faroes Fig. 32, is made known to us through the article itself in the Copenhagen Museum, illustrated by Montelius, _Civilisation of Sweden in Heathen Times_, Lond. 1888, p. 160, and through the very clear illustration and description given us by Olafsson in his _Oeconomische Reise durch Island_, 1787, translated from the Danish edition of 1780. The loom figured by Olafsson, Fig. 33, shows an advance on that of Montelius, in being provided with heddles.[H] Upright looms with a lower beam instead of with warp weights and furnished with heddles, are not uncommon. There are the well known Indian and Persian rug looms, and Du Chaillu figures one in his _Journey to Ashango Land_, London, 1867, plate facing p. 291. Randall-Maciver and Wilkin illustrate a vertical loom in use among the Kabyles, _Libyan Notes_, London, 1901, Pl. IX., and although the details of the illustration are not clear the text indicates the existence of one heddle: "The warp is decussated by means of a horizontal rod and leashes." Dr. Washington Mathews figures several Navajo looms with heddles, _Third Ann. Rep. Bureau of Ethnology_, p. 291; Ancient Peruvians also used them, as shown by Dr. Max Schmidt, _Baessler Archiv, I. pt. 1_, and so on practically _ad. lib._ But to work an upright warp-weighted loom with heddles is attended with great practical inconvenience, and this difficulty has, no doubt, been one of the chief causes of the complete discardance of this class of loom.
