Iron, silver-plated, with rich silver-gilt panels applied to the skull.
There is a trefoil piercing beneath the eye slits to assist downward vision.
The plain skull piece has a laurel wreath brow band and a narrow fluted strip running from front to back, which terminates in rosettes secured by ball-headed rivets.
Over the neck guard is a sheathing of silver gilt embossed with bands of acanthus scrolls, birds and butterflies.
Because of the workmanship, this helmet may not have been used for the hippika gymnasia at all. It is considered that it may have been a gift from a Roman official to a Syrian general in whose grave it was found.
