An incomplete Roman copper-alloy knee brooch (AD 150-250).
The axis bar, spring, pin and catch-plate are missing.
This brooch has a semi-circular head-plate. The plate is flat at the front and partially flat at the rear. The lower part of the head-plate at the rear is hollow to accommodate the missing spring. At either side of the hollow is a pierced semi-circular lug for the axis bar. One of the lugs is incomplete. The prominent bow is convex (humped) at the front and deeply concave at the rear. From the head, the sides of the bow taper inwards and then flare at the bottom. At the top the bow is 10.8mm wide and the width at the bottom is 7.0mm. The catch-plate is missing but a stub survives.
This brooch has a green patina and has an off-white deposit at the rear of the bow.
Length: 35.5mm; width: 16.4mm; thickness: 10.5mm. Weight: 5.28g.

Bayley and Butcher (2004, 179) note that after a period of perhaps a century where locally produced brooches supplied the British market, knee brooches are the first of the more general continental types seen in Britain.
