Abstract

Abstract: Metals from a votive deposit at Moita da Ladra (Tagus Estuary) dating to the eighth centurybc were studied by micro‐EDXRF, optical microscopy and Vickers testing to investigate the adoption of Phoenician innovations by indigenous communities. Artefacts are made of bronze alloys with suitable tin contents (11.6 ± 2.3 wt%) and very low iron impurities (<0.05 wt%), and were often manufactured using the long post‐casting sequence. Comparisons with indigenous and Phoenician metallurgies from western Iberia revealed a conservative technology suggesting that the spread of Phoenician innovations was very slow. In this region, the adoption of a diversified copper‐based metallurgy and reduction furnaces only seems to occur during the Post‐Orientalizing Period, c. sixth to fourth centuriesbc .
