The helmet was also worn extensively in the Greek (southern) parts of Italy in the same period.
The helmet is so-called because it was first, and is most commonly, depicted on pottery once thought to derive from the Euboean city of Chalcis.
In the front, between the two cheek pieces, was a small nasal bar to protect the wearer's nose.
The helmet would commonly have a hole pierced on each cheek piece or elsewhere in order to accept an inner lining which was made of leather.
It is likely that some of the Macedonian soldiers who ruled the rest of Greece and went on to forge a substantial Hellenistic empire also wore the Chalcidian helmet.
