Is the tangling of events in the Mediterranean around 770-760 BC in the Conventional Absolute Chronology (CAC) a reality or a construct?

This paper discusses the effect of a revision of the absolute chronology around 800-750 BC on the reading of events that led to the foundation of Greek settlements in Southern Italy in the subsequent period, from ca. 750 BC onwards. This stage is labelled here “prospecting phase”, the period of time reflected in the Odyssey, prior to the establishment of permanent overseas settlements in the Western Mediterranean by Phoenician city-states, Euboeans and other Greek communities. The following topics are addressed: 1. Update on the chronological debate “The Iron Age in the Mediterranean” 2. Some Radiocarbon results referring to contexts in Italy of the 8th century BC (Francavilla Marittima and the warrior tomb of Tarquinia) and 3. Why do dates in the CAC clutter around 770-760 BC?
