File:Enamelled terret ring fragment (FindID 182595).jpg

English: Iron Age harness fitting; Fragment of cast copper alloy terret ring inlaid with red enamel, dating to the early 1st century AD. The fragment includes one of the ‘collars’ of the terret ring (the terminals which would have enclosed the narrower bar for attaching the terret to the yoke of the chariot) and the lower section of one side of the ring itself. The ring has a flattened, subrectangular cross section which is fairly narrow at the broken end of the fragment (near the apex of the complete terret ring) but flares broadly to the trumpet collar. The surface at the trumpet end of this fragment shows an indication of the position of the bar for attaching the terret to the yoke of the chariot. This bar would have been narrow with a flattened cross section. The terret ring has 5 longitudinal, incised lines running along its outer surface and has inlaid, red enamel decoration on both the flat faces of the trumpet section. The decorative motif is of a ring and dot within a flaring arch.

Length 39.3mm, width (terminal) 17.8mm, thickness (terminal) 15.3mm, width (broken end) 7.2mm, thickness (broken end) 7.4mm, weight 27.26g.
