The ‘Acomb area’ assemblage is an unexpected chance find, acquired under the terms of The Treasure Act 1996 by the Yorkshire Museum. It consists of fragments from a gold-and-garnet decorated composite disc brooch and a dozen beads dating from the seventh century AD. We will look at how far it has been possible to recover the original appearance of the brooch, the assemblage's original context and the processes and problems of acquiring archaeological and historical knowledge from artefacts.
