Ca. 500-300 BC. A helmet comprising of hammered gilt bronze. The domed crown with front with medial ridge, with contoured double curve above the brow continuing as an occipital rib around the helmet, with pronounced arched brows and narrow flared neck guard. The crown domed with a mask-like front featuring eyes that have been carefully cut out. The round sections are each accentuated with a separately applied moulded bank. A tear-drop shaped nose guard is reaching down, moveable articulated crescentic cheeky guards with contoured edges are attached by hinges on the sides, rounded, and tapering towards the thin allowing binding. The Chalcidian-Type helmet started to replace the Corinthian-type helmet on the battlefield in the 5th century BC due to its restrictive attributes. The new versatile Chalcidian form of battle helmet enabled the owner to adapt on the battlefield. The Chalcidian helmet enabled greater sensory perception as the helmet was lighter and made in with senses in mind. By the time of the Peloponnesian War (434-402 BC) the Chalcidian helmet was the most widely distributed helmet in the Greek ranks. Good condition, heavily restored. Cf.
