Burgonet (Italian, Milan, ca. 1510–1579), dated 1543. This masterpiece of Renaissance metalwork is signed on the browplate by Filippo Negroli, whose embossed armor was praised by 16th century writers as "miraculous" and deserving "immortal merit." Formed of one plate of steel and patinated to look like bronze, the bowl is raised in high relief with motifs inspired by classical art. Met Museum.
