The findings are based on a new analysis of plant remains and ancient residue evidence. Olive use had a significant cultural and economic importance in ancient Italian societies.


The research revises earlier timelines about the introduction and spread of olive agriculture in the region. The study draws on evidence from multiple archaeological sites across Italy. Researchers analysed pollen, charred plant remains, and residue to trace long-term olive use. The findings suggest olives were integrated into daily life well before large-scale farming systems developed.
