Since ancient times, the Olive Branch has been utilized as a symbol of peace in western civilisation, and it can be found in various religions and cultures that prospered in the Mediterranean. The origins of this peace symbol are thought to be ancient Greek rituals. While the Greeks saw the olive tree as a symbol of plenty, they also saw it as having the ability to ward off evil spirits. The Olive Branch is one of the major qualities of Eirene, the Goddess of Peace, according to Greek mythology.
