An incomplete Iron Age La Tene I brooch, probably dating to c. 400-200 BC. The surviving brooch comprises of the bow and partial spring, with the foot, pin and part of the spring all missing.
At the head of the brooch is an integral spring coiled around a copper alloy axis bar, a fragment of which survives in situ. Two left coils of the spring survive, with the chord, any further coils and pin all missing. The head of the brooch survives to a width of 7.4mm, the coils being 8.2mm in diameter.
Below the head of the brooch the chord of the spring thickens pronouncedly into a highly arched bow, which (although slightly arbitrary) expands outwards at c. 120-130 degrees to 12 o'clock. The bow has a D-shaped cross section which continues to expand until the mid-point, where it reaches 8.6mm wide and 5.3mm thick. Below the mid point the bow then tapers to a relatively unabraded break just prior to the foot, sub-circular in cross section and 2.5mm wide and 2.7mm thick. Although largely unclear due to wear, the bow appears to have been decorated with a series of longitudinal incised lines, which converge at either end.
Overall the brooch is 31.1mm long and weighs 6.58g, the arch of the bow is 14.3mm high.
The relatively small size of the coils would suggest an attribution as a La Tene type 1B (Hull & Hawkes 1987: 95), although incomplete, a bow of similar proportions is illustrated by Hawkes & Hull (ibid: Plate 31), which is identified as a likely Type 1B in the absence of diagnostic features.
Class: La Tene 1B
