Greek bronze Pilos helmet, of conical form with a recessed carinated band around the lower portion. Ca. 400-300 BC. h. 35 cm. Pilos helmet takes its name from felt shepherd&#x27;s cap whose form it replicates. This helmet came into use during later Peloponnesian War, replacing earlier more closed and restrictive forms like Corinthian. Pilos was especially favored among Macedonian cavalrymen of 4th c BC. Helmet appears prominently on Macedonian coinage of Alexander the Great and his successors.
