Description: | A copper-alloy Colchester one-piece brooch of 1st century (25-60)AD date. The bow is flat with a rectangular cross-section and convex sides. It has a sharp change in angle as it approaches the head, and tapers slightly away from the head ending with a rounded tail or foot. The upper surface of the bow dips along the length centrally and contains two raised lateral lines, side-by-side, of rocker-arm decoration down the centre of this dip. The rear-facing hook has a rectangular cross-section that is 2.60mm wide and 1.33mm thick. Short plain wings each 5.30mm long, 4.07mm wide and 1.11mm thick cover the integral spring. The only decoration on the wings are two transverse grooves, one 1.29mm from each of the tips and one next to the edge of the bow. The brooch is an eight-coil version however only the four coils to the left of the bow survive. As the fourth coil turns upward, the point where the spring has broken, it starts to curve inwards towards the centre presumably ready to pass under the rear-facing hook so that it could then begin to form the coils to the right of the bow. The catch-plate is triangular with a slightly concave inner edge, 22.36mm long by 11.54mm and 0.52mm thick. Two perforations separated by a narrow stepped bridgework are present on the plate. The perforation nearest to the tail of the bow is triangular and the perforation nearest to the head is rectilinear. The return survives almost completely, turning upward until level with the start of the perforation thus ensuring the fabric behind, to which the brooch would be attached, would not be obscured by the return. The brooch has a mid greyish blue patina and a few small patches of pale green corrosion. The bordered image within the photograph of record item CAM-1F8825 is an enlarged view of the top of the brooch which is not to scale. Overall dimensions: length 61.24mm, width 18.84mm, height 17.28mm and weight 8.39g. See Hattatt, R. 2007 (p.296, fig.155, item 250 & 253) for a similar example.
