Olea oleaster, the wild-olive, has been considered by various botanists a valid species and a subspecies of the cultivated olive tree, Olea europea, which is a tree of multiple origins that was domesticated, it now appears, at various places during the fourth and third millennia BCE, in selections drawn from varying local populations. The wild-olive (Ancient Greek kotinos), which ancient Greeks distinguished from the cultivated olive tree (Ancient Greek ἐλάα), was used to fashion the olive wreath awarded victors at the ancient Olympic games. The ancient and sacred wild-olive tree of Olympia stood near the Temple of Zeus, patron of the games.
