An incomplete Roman copper-alloy developed T-shaped brooch (c. AD 75-c. 150).

Most of the pin and the lower part of the bow are missing.

The head has two hollow cylindrical wings, now 24.0mm wide, to hold the axis bar for the hinged pin. The axis bar appears to be made of iron. Between the wings at the rear of the head is a slot in which the pin hinges. Part of the copper-alloy flat loop of the pin survives in the slot. The outer ends of each wing are abraded.

The bow is sub-triangular in plan, convex and moulded at the front and flat at the rear. It projects at 45ยบ from the head then immediately curves downwards steeply in a very shallow curve before ending in a worn break. The bow tapers in width evenly from the head to the break. Adjacent to the wings the width is 9.0mm and close to the break the width is 5.6mm. At the front, the upper part of the bow has an incised saltire cross. Below the cross are two opposing sub-triangular cells for enamel. However, none survives although each cell has a brown deposit which is probably decayed enamel.

This brooch has a brown patina which is lost in places and the break at the bottom of the bow is old.

Length: 20.8mm; width of wings: 24.0mm; maximum thickness of bow: 2.9mm. Weight: 4.39g.

T-shaped brooches are very variable in the decoration on their bows although incised decoration and raised lozenges, often containing enamel, are common. Bayley and Butcher (2004:167) suggest this type is mainly South Western in distribution and dates to the later first - early 2nd century AD (c. 75-150).

A similar brooch from Bath, Avon, has been published (Hattatt 1985: 89, fig. 37, ref: 389).
