Description: | Head, upper part of the ow and upper part of the pin of a copper alloy Roman brooch, probably a varient of the first century 'birdlip' type. The head is a solid cast cylinder with the small hole down the middle holding the copper alloy axis bar for the hinged pin. It is 14.7mm wide. The pin is cast copper alloy with a circular sectioned pin, 2.3mm in diameter and 16.2mm long. It flattens and widens into a triangular plate at the head with rounded corners and a central hole for the axis bar. From the opposite corner of the plate to the pin and at about c.60 degrees to it projects a flattened rounded ended tab which fits into the underside of the head when the pin is closed.
The head tapers gradually from the cylinder into the top of the bow which is circular sectioned. The bow bends through 100 degrees and at the top of the bend is a raised collar. Beyond the collar the bow flattens into an oval cross section and narrows into a slight waist for 6.4mm before expanding out again at the point where a copper alloy 'beak' projects from the top of the bow. The beak is broken at the top with an old break and has only the start of the pronounced curve seen on birdlip brooches. Below the beak the bow is thin with a flat top, rounded sides and slightly convex back. It ends in an old break.
The piece is 34.2mm long, 24.7mm top to bottom, and 9.7mm wide at the bow by 7.9mm thick at the head (widest/thickest points) It weighs 13.31 grams.
The collar and 'beak' are similar to other birdlip brooches but the head is different as they usually have a trumpet shaped head or a circular head with a raised ridge behind which is the spring or hinge. However the general form appears correct for the 1st century AD. | Subjects: | Birdlip | Source: | Portable Antiquities | Creator: | WALKER, Liz - Portable Antiquities Scheme | Identifier: | http://www.findsdatabase.org.uk/hms/pas_... | Language: | en-GB | Go to resource |
