Description: | A complete copper alloy Roman composite plate brooch. At the centre is a raised square panel with a knurled outer edge which is c.1.5mm wide, and a central square recess which measures 10.56x10.15mm. There us a trace of turquoise and possibly yellow enamel in one corner, which is most likely to have been millefiori enamel in a chequerboard pattern. This raised panel is set 2.85mm above a square plate with a square cut from each corner and each side has a knurled line with either a narrow groove above or below or both. There is a flat circular disc extending from the centre of each outer edge; each has a raised border, followed by a concentric moulding and at the centre is a circular ring which is 2.37mm in diameter and with a central recess that is likly to have held enamel. Each has a pale residue ?cement present. The outer edge of one roundel is damaged and there is a piece missing from the square plate below the raised panel on one side. The reverse of the square panel is domed and hollowed and has a diameter of 16.45mm. At its centre is a circular moulded boss which is hollowed conically. It is likely that this boss on the reverse was in place to aid the lathe-turning of the mould of the brooch. The hinged copper alloy pin is complete, but bent and is held by two perforated lugs which are elongated D-shaped in plan. Iron corrosion on the lugs suggests that the axis bar is iron. The catchplate is intact and is 10.7mm in length and 7.3mm deep and has seven transverse grooves at the fold. Even mid-dark brown patina. It is 38.3mm in length, 38.1mm in width, 1.3mm thick and weighs 9.32g. This brooch is similar to a quadriform brooch from Belton, Norfolk (Hattatt 1989, 160 no. 1820 fig 75). It would appear that this is an unusual and rare type of brooch, which shows broad similarities with the more numerous Lozenge and Disc brooches which generally date to the 2nd century AD. Examples on the continent include those from Augst (Riha 1979, Type 7.20 197 no,1698 Taf.65).
