Galea (helmet)
A galea was a Roman soldier's metal helmet, most famously worn by the heavy infantry of the legions. Some gladiators, specifically murmillo, also wore bronze galeae with face masks and decorations, often a fish on its crest. While details varied over time, all Roman galeas from the Republic era through the Principate featured the same basic design - a bowl to protect the skull, a neck guard, a deflector band to protect the forehead and cheek plates to protect the face. The exact form, type of metal, and design of the helmet varied over time, between differing unit types, and also between individual examples – pre-industrial production was by hand – so it is not certain to what degree there was any standardization even under the Roman Empire.
Originally, Roman helmets were influenced by the neighboring Etruscans, people who utilised the "Nasua" type helmets. The Greeks in the south also influenced Roman design in its early history.
The primary evidence is scattered archaeological finds, which are often damaged or incomplete; secondary evidence includes period depictions of galeae, generally in bas-relief sculpture and mosaic.
Helmet types
in his book The Armour of Imperial Rome, published in 1975, classified into broad divisions the various forms of helmets that were found. He classified four main types of helmets for heavy infantry and thirty different types of cheek guards.Helmets used by gladiators were quite different from military versions.
Legionary infantry helmets
- Montefortino helmet
- Coolus helmet
- Imperial Gallic helmet
- Imperial Italic helmet
- Ridge helmet, first depicted on coins of 4th-century AD emperor Constantine I
Helmet crests
There is some evidence that legionaries had their crests mounted longitudinally and centurions had them mounted transversely. Crests may have been worn at all times by centurions in the early empire, including during battle, but legionaries, and centurions during other periods, probably wore crests only occasionally.
