BROOCH

Unique ID: LIN-136BA2

Object type certainty: Certain
Workflow status: Published Find published

An incomplete copper alloy umbonate brooch dating to the Roman period (c. AD 100 - AD250). The brooch is circular in plan with four projections extending from quarter points around the circumference: four rounded knops, behind one of which is an incomplete suspension loop at the apex. Behind the loop are two lugs which contain a small part of the copper alloy hinge. Behind the bottom most knop is an integral catchplate. The copper alloy pin is intact.

The main body of the brooch is convex and decorated with an outer recessed border. The domed surface contains two concentric rings of recessed triangular cells pointing towards a central ring and dot motif. All of the triangular cells are, or have been, filled with alternating blue and red enamel, and those between are of reserve metal.

Umbonate brooches of this type are frequently encountered finds on military and civilian sites throughout Britain (Bayley and Butcher: p. 173). Hattatt (2000) dates one from Owmby, Lincolnshire (p. 350, fig 209, #128) to the 2nd Century. Another similar example on the PAS database is WAW-0FB717.
