File:Roman Brooch, Hinged T-shaped with Serrated Edge (FindID 433344).jpg

English: A Roman copper-alloy enamelled hinged T-Shaped brooch with toothed edge. The brooch is largely complete, save for one of its crossbar arms and hinged pin, in addition to some decorative damage long the toothed edges and missing enamel inlay. From the top of the brooch, the crossbar has an angled flat front and a curved reverse face, holding the remains of an iron hinge and central gap, which would have held the now missing pin. A large toothed crest on the upper bow has a hole in its upper lobe, which may have been intended for a chain, but is similar to earlier Colchester types which held a chord in this position (Bayley and Butcher 2004, p95). The brooch body itself is quasi-triangular in plan, with raised ridges running the perimeter edge and tapering to the decorated foot; at the outside of the raised perimeter ridges are serrated decorations. The bow has raised crisscross patterns across it forming diamond shapes in the middle. There still remains some yellow enameling within these diamond shapes, although the triangular cells are now empty. The vertically-oriented catchplate has a curled outer edge to hold the pin. The foot knop is highly elaborate and consists of a ribbed collar at the termination of the previously mentioned perimeter ridges, followed by a triple-beaded collar, with a thicker central bead decorated with vertical ridges; the foot then terminates in a further smaller rounded knop with uncertain decoration. The wings measure 17.04mm, the length measures 35.84mm, the width of the bow at its widest point measures 11.11mm and at it's narrowest 4.30mm.

Cf. Bayley and Butcher 2004, Fig. 75, No. 225. Although Hattatt (2007, Fig. 163) dates similar brooches to the 1st-2nd century AD, the example given here from Bayley and Butcher comes from contexts dating to AD 400+. Therefore, a suggested date range of 1st-4th century AD is given here.
