An equestrian statue is a statue of a rider mounted on a horse, from the Latin eques, meaning 'knight', deriving from equus, meaning 'horse'.[1] A statue of a riderless horse is strictly an equine statue. A full-sized equestrian statue is a difficult and expensive object for any culture to produce, and figures have typically been portraits of rulers or, in the Renaissance and more recently, military commanders.
Although there are outliers, the form is essentially a tradition in Western art, used for imperial propaganda by the Roman emperors, with a significant revival in Italian Renaissance sculpture, which continued across Europe in the Baroque, as mastering the large-scale casting of bronze became more widespread, and later periods.
Statues at well under life-size have been popular in various materials, including porcelain, since the Renaissance. The riders in these may not be portraits, but figures from classical mythology or generic figures such as Native Americans.
