Among the Chalcidian helmet types, the fifth and last typology, corresponding to the Kunze group VII (Pflug, 1988, p.138), was characterised by the presence of detached cheek-guards. By the end of the 5th century BC, the fixed cheek-pieces had been entirely abandoned on the Chalcidian helmets for the more versatile hinged cheek pieces. As is the case with most of the Greek helmets in 5th and 4th century B.C., very few originals have been found on the Greek continent. Several district regional workshops produced such helmets by the 5th century B.C.: mainland Greece, Black Sea Coast, Thrace, Southern Italy and Iberia.
