A laurel wreath is a circular wreath made of interlocking branches and leaves of the bay laurel (Laurus nobilis), an aromatic broadleaf evergreen, or later from spineless butcher's broom (Ruscus hypoglossum) or cherry laurel (Prunus laurocerasus). In Greek mythology, Apollo is represented wearing a laurel wreath on his head. In ancient Greece wreaths were awarded to victors, both in athletic competitions, including the ancient Olympics made of wild olive-tree known as "kotinos" (κότινος), (sc. at Olympia) and in poetic meets; in Rome they were symbols of martial victory, crowning a successful commander during his triumph. Whereas ancient laurel wreaths are most often depicted as a horseshoe shape, modern versions are usually complete rings.
