This was sold as two gauntlets, one original. I expect that it hadn't been long since they had been displayed together on a suit. They serve to illustrate a lot of things that differentiate a real gauntlet from a much less well executed reproduction. Ignoring the etching and the remains of gilding, the form of the cuff, the form of the back of hand and the interior are dead give aways.
Gauntlet circa 1590
Italian. Good quality Italian gauntlet for the left hand (fingers and thumb missing) etched in the characteristic Pisan fashion. One piece cuff joined with a rivetted overlap at the inside of flared form with inward turned, roped roll at the edge and a parallel raised, roped line with etching in between. Plain inward turn at the wrist. Back of hand covered by 5 plates and a knuckle plate with rounded areas over each knuckle. Hand plates with internal assembly marks in the form of 5 chisel marks at the edge. Retains some gilding. Ends of the metacarpal plates at the thumb side with multiple decorative notches, single notches on the opposite side. Associated with a lower quality modern copy of a right gauntlet with similar etching. Modern copy not forming a pair. [inv. num. A-244]
