Description: | An incompletes cast copper alloy and gilded plate brooch of Roman date (AD 100 ? AD 250). Length 31mm, diameter 27mm, thickness of plate 3.0mm. Weight 6.86g.
The brooch is circular in plan and has a central circular cell that is 15mm in diameter. At the front the cell is slightly convex and has a small circular depression at the centre. The cell is surrounded by a shallow channel, about 5.0mm in width, decorated with repetitive S-shaped motifs. There is a raised peripheral rim. The rear face is flat and has an incomplete perforated lug at the top to accommodate a copper alloy axis bar that secures a spring of four turns (two either side of the lug). The internal chord is intact but the pin is missing. The catch-plate is incomplete and extends beyond the edge of the plate. A small amount of gilding has survived within the channel at the front and the rear face has traces of tinning. The brooch has a old damage in the form of a small irregular shaped hole in the plate within the central cell. It is generally corroded and in poor condition.
It is possible that the regularly spaced S-shaped motifs have been stamped. However, it is also possible that the motifs were created by rouletting with the use of a lathe. The small circular depression at the center of the cell may have functioned as a ?centre-pop? that enabled the brooch to be mounted securely in a lathe so that the brooch could be turned concentrically. The cell may have been filled with a glass setting although there is no evidence for such a setting or the remains of any adhesive material. | Format: | text/html | License: | http://creativecommons.org/licenses/by-sa/3.0/ | Publisher: | The Portable Antiquities Scheme | Rights holder: | The Portable Antiquities Scheme | Subjects: | archaeology | Temporal: | 100
