Etruscans with olive trees. For the Etruscans, olive oil was also a medicine
The appreciation of the Etruscans for the olive oil was not limited to the table and religious use (https://www.pilloledistoria.it/5877/storia-antica/luso-dellolio-doliva-presso-gli-etruschi), but went so far as to make it an indispensable complement for many daily chores.
The lighting first of all:the one of poorer quality was not thrown away at all, but used to light the lamps, both public and private, an alternative and practical use of oil started in ancient times and practically never finished.
As a medicament instead, olive oil proved to be excellent for softening the skin of the body and to soothe muscle pain caused by fatigue following sports or military activity, a use of food that is anything but exclusive to the Etruscans, but common to many other peoples of the past.
