Abstract: | A small amber fragment from the period of Roman occupation of Numantia (Garray, Spain) was characterised by Fourier transformed infrared spectroscopy and optical microscopy. The material was found to be a polystyrene-like material, which is a very rare fossil resin known as Siegburgite or class III amber. Until now, this material was found in Europe only at two sites, both localised in Germany, and it is the first time that this type of amber was identified in wrought archaeological artefacts. The discussion includes the applicability of the method to distinguish false from true and amber of different origins, its use and trading as well as a hypothesis for a transport route. The study highlights the need for a more systematic study of archaeological amber remains. The finding also proves the exploitation and trading of local, non-Baltic amber deposits throughout the Roman Empire. |
