Greek "Illyrian type" bronze helmet from Argolis (6th–5th centuries BC).
The "Illyrian" or "Greco-Illyrian" type helmet is an archaeological term that describes a style of bronzehelmet, which in its later variations covered the entire head and neck, and was open-faced in all of its subsequent 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.[note 1]
According to archaeological evidence, the "Illyrian" type helmet evolved from the Kegelhelm (or Kegel type) of the Archaic Period found in Argos. The earliest "Illyrian" type helmets were developed in a workshop located in the northwestern Peloponnese (possibly Olympia), although the first Type II "Illyrian" helmets were created in Corinthian workshops. The first Type III helmets were created in workshops situated somewhere on the Illyrian coast of the Adriatic. The "Illyrian" type helmet did not obstruct the wearer's critical senses of vision though the first two varieties hampered hearing. There were four types of these helmets and all were open faced:
Type I (c. 700–640 BC) left the neck unprotected and hampered hearing.
Type II (c. 600 BC) offered neck protection and again hampered hearing.
Type III (c. 550 BC) offered neck protection and allowed better hearing.
Type IV (c. 500 BC) was similar to Type III but hearing was not impaired at all.
The Illyrian type helmet was used by the ancient Greeks,Etruscans,Scythians, and became popular with the Illyrians who later adopted it. A variety of the helm had also spread to Italy based on its appearance on ivory reliefs and on a silver bowl at the "Bernardini" tomb at Praeneste. The helmet became obsolete in most parts of Greece in the early 5th century BC. Its use in Illyria had ended by the 4th century BC.
^Naming conventions and typology of ancient helmets are of modern origin and do not reflect contemporary usage. (Connolly 1998, p. 60: "Terms such as 'Illyrian' and 'Attic' are used in archaeology for convenience to denote a particular type of helmet and do not imply its origin.")
^Snodgrass 1999, pp. 76, 95; Sekunda 1998, p. 53: "Figure D2, based on a Lakonian warrior statuette from Dodona, wears a helmet of the Illyrian type, so-named because a large number of early finds came from Illyria. However, it is now clear that it was also extremely popular in the Peloponnese, which is the most probable area of origin."
^Treister 1996, p. 65: "The earliest variants of type 3 of the Illyrian helmet, dating primarily to the second half of the 6th century B.C., belong to the production of the workshops situated somewhere on the Illyrian coast of the Adriatic."
^ abSnodgrass 1999, p. 52: "Another common form, superficially similar to the 'Insular', is the so-called 'Illyrian' helmet, in fact a purely Greek type which perhaps originated somewhere in the Peloponnese in the earlier seventh century, and only centuries later found its way to Illyria and other barbarian lands."
