Incomplete and heavily worn cast copper alloy Roman umbonate brooch. The central part of the brooch and part of the surrounding flange survives. When whole the brooch would have been sub-circular in plan and domed in section. The front of the brooch carries a design of enamel inlaid cells with a wheel of triangular cells at the centre framed by a recessed circular groove and beyond this, decorating the outer flange, a ring of alternating outwardly and inwardly pointing arrow-shaped cells. Traces of red and blue enamel survive, with the circular groove being red and the other cells being partially red. On the reverse of the brooch traces of the hinged pin fittings survive. The copper alloy of the brooch has a powdery light green patina. Brooches of this type are typically dated AD 100-250.
