This horse derives from Giambologna's model for his equestrian monument to Cosimo I. Only a few casts are known, all of small size of slightly variable height (15 to 16 cm). Even though long regarded as Florentine circa 1600, this model is now attributed to Barthélemy Prieur. Two other bronze casts, one in the Bargello Museum in Florence, the other from the Robert H. Smith collection in the National Gallery of Art, Washington, have clipped untextured manes comparable to the present bronze. Another cast, with a more free-flowing mane, was formerly in the collection of Michael Hall (Christie's, New York, 11 June 2010, lot 169).
The present bronze perfectly illustrates the majestic motion of a pacing horse. Its anatomy is accurately described, in a realistic manner, particularly in his swollen veins, the details of the horse's shoes, the folds of skin visible on his arched neck and his bent hock.
