Extremely widespread in the seventh century BC, the Corinthian helmet provided maximum protection with its nasal and its broad cheek plates. The curved profile of the back part of the Louvre example and the angular side openings mark a stage in the development of this type of helmet. The engraved decoration is lavish: palmettes, female sphinxes, and lions refer to proto-Corinthian ceramics and are inspired by the Greco-oriental repertoire employed during the orientalist period.
