A similar example is illustrated in Kershaw (2010). "The interweaving tendrils of this motif,which adorns a prolific series of Anglo-Scandinavian disc brooches, recall the loops formed by ribbon-shaped Borre-style gripping beasts (Wilson 1976, 504-6)."
"The Borre style was current inScandinavia from the late ninth to the late tenth century. This timeframe is supported by dendrochronological information obtained from sites with diagnostically Borre-style material (such as Gokstad (900-905), Tune(905-910), Borre itself (c900), Fyrkat (980)and Trelleborg (980/1)) in addition to coin-dated hoards (Bonde and Christiansen 1993;Christensen and Bonde 1991; Wilson 1995,107-11). In the British Isles, the style is likely to have emerged with Scandinavian activity and settlement from the late ninth century." from Kershaw (2010.
