The "Illyrian" or "Greco-Illyrian" type helmet is a style of bronze helmet, which in its later variations covered the entire head and neck, and was open-faced in all of its forms. Its earliest styles were first developed in ancient Greece, specifically in the Peloponnese, during the 8th and 7th centuries BC (700–640 BC). Accurate representations on Corinthian vases are sufficient to indicate that the "Illyrian" type helmet was developed before 600 BC. The helmet was misleadingly named as an "Illyrian" type due to a large number of early finds coming from Illyria.
