Pompeo della Cesa was the most renowned Italian armorer of the late 16th century. His clients included some of the most celebrated noblemen of their day--the two Spanish kings Philip II and III; Alessandro Farnese, Duke of Parma and Piacenza; and Vincenzo I Gonzaga, Duke of Mantua. He is known to have maintained a large workshop in Milan's castle--the so-called Sforza Castle. The original owner of this armor remains unidentified. However, armors made for patrons of noble rank were typically of very high quality like this one. Ostentation was of paramount importance for public spectacles such as tournaments or parades. Most wealthy patrons afforded the additional expense of embellishing their armors. The most frequently used decorative technique for armor was etching, seen here, in which acid was used to "bite" into exposed surfaces of the armor's steel plates to create permanent patterns. The etched and gilded decoration of this armor features vertical bands of strapwork enclosing cartouches which in turn contain allegorical figures, classical warriors, and trophies. The decoration represents Pompeo's classic style of armor decoration, one which is found on over forty surviving suits. These and other decorative patterns were normally recorded in pattern books from which the prospective client made his selections.
