The Greeks use of the acanthus leaf as a decorative architectural element dates back as early as 500 BC, when lavishly carved acanthus leaves (based on the popular anthemion design in Greek architecture) began appearing on the beautiful capitals of slender and elegant, fluted Corinthian columns. These first carved acanthus leaves, with their sharp points, deeply carved corners, and sharp ridges between the lobes, were clustered together so that their clear shadow lines could easily be seen from a distance. A symbol of eternal life and rebirth, acanthus leaves were perfect for decorating temples and monuments to the gods. Famous examples include the Temple of Zeus in Athens and the Temple of Apollo Epicurius at Bassae in Arcadia, the oldest known use of acanthus in architecture.
