Description: | An incomplete copper-alloy Late Iron Age - early Roman Langon Down brooch dated AD 25-60. The pin would have been sprung and held within a cylinder spring case, and weighs 5.12g. This cylinder is formed from the expansion of the top and bottom edge of the wings which curve around forming a now incomplete encasement. This encasement is likely to have had a small notch for the pin to exit the encasement from. The pin no longer survives. The curved wings have a width of 19.3mm and height of 6.3mm. The ends of the wings are open and seem not to have had end-caps. No decoration is visible on the external surface of the wings and the terminal end of the right wing appears irregular and may represent a worn break. The start of the bow is defined by a straight transverse line where the bow starts to rise up from the wing. It is possible that some tiny pitted dots are present on the wing just above the start of the bow. If these tiny dots are intentional rather than the result of corrosion or slight damage they have a diameter no larger than a tiny pin prick of less than 0.3mm. The bow has a sub-triangular cross-section formed of a flattish slightly convex reverse and upper surface consisting of a central rib flanked by a flute to either side. The bow has a width of 10.0mm and thickness of 4.5mm by the wings. At the foot the bow has a rounded terminal. The width of the bow just before it starts to taper to the rounded point is 5.2mm with a thickness of 1.3mm. The curved bow has a length of 51.0mm. The curve of the bow seems to have been squashed partially out of shape and now has an angular nature to the profile. No surface coating is visible on this brooch however the surface does seem to be slightly abraded.On the reverse of the bow a central ridge is present running from the very tip of the foot for a length of approximately 25.4mm. This ridge has a width of 1.4mm and rises to form the catch-plate. It is uncertain what form the catch-plate took. The ridge rises to a height of 2.2mm for a length of 5.3mm from the foot then reduces to little more than a scar. This ridge then increases in height again 15.6mm from the foot to a maximum height of 3.3mm for a length of 6.7mm. The edge of this part of the catch-plate, nearest to the top of the brooch slopes to join the underside of the bow where the catch-plate ridge fades away becoming indistinct and terminating. The catch-plate may have had an openwork aperture and these two areas of increased ridge height represent the areas where the catch-plate emerged from the back of the bow. Alternatively the catch-plate may only have consisted of two projections separated by a gap and not joined together above an aperture. No return survives and it is uncertain whether one was ever present. This brooch has a straight maximum length of 39.7mm and maximum width, across the curved wings of 19.3mm.
