Abstract

Analysis by SEM and EDAX of the remains of two ancient fibulae, identical in material (bronze), design (leech-shaped), cut and size has revealed that, despite appearances to the contrary, they were not cast in the same mould, presenting substantial differences in the microstructure and composition of the alloy. Moreover, EDAX investigation has produced an unexpected result, as one of the two alloys has been found to present little less than 4% aluminium, despite having been buried for over 2000 years in a ground rich in halides, fairly acidic and constantly waterlogged.
