Knowledge of glass trading in protohistoric Southern Italy has been limited by a lack of archeometrical data available to date, preventing comparison with the well-known Northern Italian context. The aim of the present work is to help fill the data gap for Southern Bronze-Iron Age vitreous items and enable a general overview of protohistoric Italian glass supply routes. The paper presents physical-chemical data for 61 vitreous items from 11 Southern Italian sites, dated from the beginning of the Bronze Age up to the Archaic period (22nd–6th century BC), ensuring a complete diachronic analysis. SEM-EDS, EMPA, LA-ICPMS, and XRD analyses permitted definition of the raw materials and manufacturing techniques employed, as well as determination of item provenance. The sample set exhibits great variability of glass chemical types, including plant ash glass, mixed alkali, and natron samples. A complex picture emerges, mostly as regards the different natron glass typologies (High-Zr, Low-Zr, Black, etc.) and their rapid technological evolution in the early 1st millennium BC. Taking into account the data reported in this study and those available in literature for both Northern and Southern Italian Bronze-Iron Ages items, this work demonstrates the existence of different trade routes for the first time. This is especially true for the Early/Middle Bronze Age periods, with Northern Italy involved in trade with Central Europe, and South already involved in Mediterranean trade circuits.

Abstract

Knowledge of glass trading in protohistoric Southern Italy has been limited by a lack of archeometrical data available to date, preventing comparison with the well-known Northern Italian context. The aim of the present work is to help fill the data gap for Southern Bronze-Iron Age vitreous items and enable a general overview of protohistoric Italian glass supply routes. The paper presents physical-chemical data for 61 vitreous items from 11 Southern Italian sites, dated from the beginning of the Bronze Age up to the Archaic period (22nd–6th century BC), ensuring a complete diachronic analysis. SEM-EDS, EMPA, LA-ICPMS, and XRD analyses permitted definition of the raw materials and manufacturing techniques employed, as well as determination of item provenance. The sample set exhibits great variability of glass chemical types, including plant ash glass, mixed alkali, and natron samples. A complex picture emerges, mostly as regards the different natron glass typologies (High-Zr, Low-Zr, Black, etc.) and their rapid technological evolution in the early 1st millennium BC. Taking into account the data reported in this study and those available in literature for both Northern and Southern Italian Bronze-Iron Ages items, this work demonstrates the existence of different trade routes for the first time. This is especially true for the Early/Middle Bronze Age periods, with Northern Italy involved in trade with Central Europe, and South already involved in Mediterranean trade circuits.
