Of Type IIIB, hammered from bronze sheet, of domed form. The helmet has a short flaring neck-guard and straight protective cheek guards. There are two raised parallel ridges running front to back across the crown, with a button pin at the centre front.
This is a purely Greek form of helmet with its origins in the north-western Peloponnese of the early 7th century. Many such helmets have been found in the Peloponnese, including at Olympia. There is a Lakonian (Spartan) bronze figure of a warrior found at Dodona, depicted wearing an Illyrian helmet, supporting the popularity of this type of helmet in the Peloponnese in the Archaic Period.
Due to a number of early finds of such helmets on the eastern coast of the Adriatic Sea, in modern scholarship the form became known as Illyrian. There were three main phases of development of the helmet and this example belongs to Type IIIB: For discussion of Type IIIB, see H. Pflug, 'Illyrische Helme', in A. Bottini et al. Antike Helme, Mainz, 1988, 55-9. For further reading see A. M. Snodgrass, Early Greek Armour and Weapons. From the End of the Bronze Age to 600 B.C., Edinburgh, 1964.
