Filippo Negroli and Brothers, Italian, c. 1510–1579
Armor of Emperor Charles V, Milan, 1539
embossed and gold- and silver-damascened steel; brass and leather
Patrimonio Nacional, Real Armería, Madrid,

Because of the decoration over the elbows, shoulders, and helmet, this armor is known as the "Mask Garniture." (Garnitures are sets of armor with interchangeable parts that adapted the suit for use on horseback or on foot, in tournaments or on the battlefield.) It is the only suit of armor signed and dated by Filippo (in an inscription under the visor) and is thus considered the key work of the Negroli workshop. The exquisite damascening, a technique for inlaying the gold designs, is the work of Filippo’s talented seventeen-year-old brother, Francesco.
