“This masterpiece of Renaissance metalwork is signed on the browplate by Filippo Negroli, whose embossed armor was praised by sixteenth-century writers as “miraculous” and deserving “immortal merit” … The graceful mermaid-like siren forming the helmet’s comb holds a grimacing head of Medusa by the hair. The sides of the helmet are covered with acanthus scrolls inhabited by putti, a motif ultimately derived from ancient Roman sculpture and wall paintings.” - Metropolitan Museum of Art
