File:Medieval annular buckle (FindID 150130).jpg

English: A worn cast copper-alloy artefact, probably a medieval buckle. Convention suggests that this object be classified as a buckle rather than a brooch due to the absence of the highly decorative features associated with annular brooches as well as the absence of an obvious pin constriction. The annular frame has an external diameter of just under 30mm and an internal diameter of 23.6mm. It has a sub-circular cross-section. Two tranverse grooves next to each other on one face may have acted as a pin rest. The frame is heavily pitted and has corroded to a dark grey colour. This contrasts with the red-brown colour of the pin. The plain pin has been cast and looped round the frame. It tapers to a point which, due to wear, no longer reaches the frame; the pin is 27.6mm long. The pin shaft is semi-circular in section. Annular buckles are difficult to date due to the lack of diagnostic decorative features. However, examples found in London illustrated in Egan and Pritchard (1991, 57-58) tend to come from late 14th-century contexts.
