Shetelig, H.Osebergfunnet (1921), vol. 11, 239, nos. h, i: vol. m, 226, fig. 214. Shetelig, H. and Petersen, J.Viking Antiquities in Great Britain and Ireland (1940), pt. v, 1940, 26, fig. 17. The two somewhat similar-looking mounts from a Viking tumulus on Oronsay, found in 1891 (Proc. Soc. Ant. Scot., XLI (1906) 438, figs, i and 2, and Shetelig, H. and Grieg, S.Viking Antiquities in Great Britain and Ireland (1940), pt. II, p. 44) must have had a quite different use. They were both hinged at one end, and their backs are flanked with deep flanges which must have fitted over a wooden bar or other element which moved in one piece with its metal cover. I am indebted to Miss Audrey Henshall, F.S.A., for detailed drawings of the backs of these two mounts, which were later adapted as brooches by their Viking owners.
