Celtic Concho, 22 x 22 mm, Antique brass plated, 2 rivet pins
The ring cross is the oldest symbol of the Celtic empire and also from Sweden, where it is on Gotland as a triumph Cross and otherwise to be found as a mid-summer cross. The sechsblätterige star pattern on the Scottish Cross-slab Cladh a'Bhile has its equivalents in Gotland. That link also has the line Sueno Stone, a Scottish stone image with Nordic motifs that should be named after the Danish king Sven.
