French archeologists uncovered thirty metopes belonging to the Athenian Treasury scattered in the Sanctuary of Apollo at Delphi between 1893 and 1894. According to Pausanias the Athenians commissioned the Treasury to celebrate their victory over the Persians at the battle of Marathon in 490 BCE. The sculptures depict myths about the labors, of the Pan-Hellenic hero, Herakles, and tasks of the Athenian newcomer, Theseus. The metopes contain stylistic elements from multiple geographic locations and both the Late Archaic and Early Classical periods. The visual evidence challenges the scholarly assumption that Late Archaic artists were incapable of experimentation through the integration, combination and juxtaposition of multiple styles. The advanced state of the Late Archaic style during the 480s indicates the large artistic repertoire to which the commissioners, planners, and sculptors would have been exposed. This paper examines elements in seven of the metopes that indicate experimentations by the artists of the Athenian Treasury.
