The Chalcidian type of Greek helmet was, in essence, a lighter and less restrictive form of the Corinthian helmet. Later Chalcidian helmets had hinged cheekpieces that were anatomically formed to fit closely to the face. The cheekpieces tended to curve upward towards the eye, where there were large circular openings that provided a wider field of view compared to the Corinthian helmets. Chalcidian helmets also featured an opening for the ear and a neck guard, which conformed closely to the contours of the back of the neck and terminated in a flanged lower border.
