Olive presses in the South-East Peloponnese (Lakonia-Messinia) during antiquity: The origins of olive cultivation and the accompanying extraction of olive oil as a productive process are lost in time, corresponding to a lifespan of millennia and a condensed experience of innumerable years. Our knowledge of it through written sources ―Greek and Latin authors from Ancient and Byzantine times― is documented by scarce archaeological data, which are being completed as far as possible with information about the contemporary productive process, and in particular that dating to before the Second World War.
