the exterior edge itself folded down. Two pieces of equal length were used, abutting at the back of the helmet, although the sinister strip was not found with the helmet. The dexter strip is long and tall, and between its bottom and the bottom of the brow band, leaves a hollow high gap. Seven or eight slots, each between and wide, were cut for every of the strip. One ring of mail was placed into each slot, and a piece of iron wire in diameter was slotted through to hold them in place. The mail suspension strip was held on by silver rivets with domed heads; only two survive, though five were probably originally used. Suspended from the cap are two cheek guards and a mail curtain. The cheek guards are made from individual pieces of iron and at their maximum dimensions are approximately long and wide. They are curved inward both laterally and longitudinally, and each held to the brow band by a single hinge. Both hinges are made of two pieces of iron, approximately long and wide, that were bent in half over a circular rod and then cut to create matching slots; the upper dexter piece has four slots and the lower piece three—one of which is broken—a pattern that is reversed on the sinister side. The upper halves fit over sections cut out of the brow band, the lower halves over the cheek guards, and all four pieces are held in place with two iron rivets. The slots mesh together, and are held in place by diameter iron pins, the sinister of which is missing and has been replaced. The mail is remarkable in consisting of forge-welded links, rather than the far more common riveted links. The helmet was found to be made of iron, with applied brass-work containing approximately 85% copper. It is very like the helmets depicted being worn by Anglo-Saxon Northumbrian cavalrymen on one of the Pictish Aberlemno Sculptured Stones, believed to depict the Battle of Dun Nechtain of 685. Decoration The helmet has two low crests of brass, one running from front to back, the other from side to side, forming a cross shape when viewed from above. The brass banding within the crests bears a Latin inscription: IN NOMINE : DNI : NOSTRI : IHV : SCS : SPS : DI : ET : OMNIBVS : DECEMVS : AMEN: OSHERE :
