One of the earliest and most iconic types of Greek helmets was the Corinthian helmet, which became popular in the 6th century BCE. This helmet, named after the city of Corinth, was known for its full-face coverage, with only small openings for the eyes and mouth. It provided exceptional protection for the head and face, which was crucial in hand-to-hand combat, especially during the Phalanx formation. The Corinthian helmet was often elaborately designed, made of bronze, and had a distinct appearance, with a pronounced nose guard and a crest that ran from the front to the back of the helmet. Its heavy construction, however, limited vision and hearing, which made it less practical for certain types of warfare and led to modifications in later designs.

In contrast, the Attic helmet, which emerged around the 5th century BCE, was designed for improved visibility and comfort. It had a simpler, more open-faced structure compared to the Corinthian helmet, with a raised ridge that protected the top of the head and flared cheek guards that shielded the sides of the face while allowing for greater peripheral vision and better hearing. The Attic helmet was lighter and more practical for the close-quarters combat of hoplite soldiers. It was widely used during the Peloponnesian War and was often made of bronze or iron. The Attic helmet’s design influenced later helmets in both Greek and Roman warfare.

Another type of helmet used by the ancient Greeks was the Phrygian helmet, which was influenced by the peoples of Asia Minor and became popular in the 4th century BCE. This helmet featured a pointed or cone-shaped design, resembling the Phrygian cap worn by people in the eastern Mediterranean. It had a distinctive crest that sloped backward, providing both protection and an intimidating appearance. The Phrygian helmet was made from metal or leather and was often decorated with a plume or a crest. Its design was lighter than the Corinthian helmet, offering better comfort and mobility while still providing adequate protection for the head.

During the later Hellenistic period, the Greeks also adopted various forms of the Krepis and helmet types seen in the armies of Alexander the Great, which were influenced by encounters with other cultures. The Hellenistic helmets were often more streamlined and less bulky, reflecting a shift towards greater flexibility and adaptability in battle. These helmets frequently included a brow guard and were sometimes equipped with additional protection for the neck and shoulders, showcasing a trend toward more ergonomic designs suited for both heavy and light infantry.
