In the Bible (Jeremiah, Ecclesiastes, Hosea), the olive tree is a symbol of beauty, justice and knowledge. For us it also has exorcising functions: in the homes of our elders, the blessed olive branch, renewed every year on Palm Sunday, was inevitable at the head of the bed, thaumaturgical protection from every illness.

In the Christian tradition, oil is as sacred as the olive tree that produces it: it is in fact the matter chosen by God as a channel of transferring some of His graces to men, expounding holiness in the Sacraments.

From the first moment it appeared in every civilization, the olive tree was felt as a sacred symbol of peace, fertility, purification, victory; a symbol that is repeated, with significant continuity, in all cultures of the Mediterranean.

In Greek mythology, the olive tree was born as a peace treaty after the dispute between Athena and Poseidon; and it is believed that the plants that today grow on the Acropolis derive precisely from that primitive plant, venerated in the Erechteion.
