File:Aesica brooch rosette varient (FindID 986943).jpg

English: An incomplete Roman copper-alloy silvered aesica type brooch, possible rosette variant, dating to c. AD 25 - 75. The brooch is largely complete but is missing all but the head of the pin. The wings are cylindrical housing an iron axis bar. At the centre of the wings, on the underside of the brooch is a small rectangular notch for the articulation of the pin and the head of the pin is still attached. The fronts of the ends of the wings are decorated with vertical grooves and ridges. The upper bow projects forward from the wings, it is triangular in cross-section, it widens slightly then tapers to a blunt point, creating an arrowhead shaped projection. The upper bow projects slightly over the top of the middle bow, so that the arrowhead is visible. The middle bow is oval and has a rectangular cross-section. It is white metal coated. Projecting from the lower edge of the oval plate  is the fan-shaped leg of the bow. The leg is decorated two pairs of incised longitudinal lines. At the bottom left corner is a small rounded knop, the right side one lost to an old break. At the rear of the leg and extending behind the mid bow is a large, curving catchplate.

Length: 48.61 mm

Similar brooches are recorded in Bayley & Butcher (2004: 154-155). There the authors note that these are 'typically seen as a degenerative variant of the Rosette brooch, and in the absence of secure dating evidence assign it a likely mid-first century date range'. A similar date range seems likely here.

It also has similarities with SOM-FBBE77.
