Equestrian Statue of Marcus Aurelius in the context of "Ancient Roman art"

The Capitoline Museums (Italian: Musei Capitolini) are a group of art and archaeological museums located on the Capitoline Hill in Rome, Italy. Their principal buildings are the Palazzo dei Conservatori and the Palazzo Nuovo, which face each other across Piazza del Campidoglio, the square designed by Michelangelo in 1536 and completed over the course of the following centuries.

The museums are primarily dedicated to the art and history of ancient Rome, with a particular emphasis on Roman sculpture. The collection include celebrated works such as the Equestrian Statue of Marcus Aurelius, the Capitoline Wolf and the Dying Gaul, alongside inscriptions, coins, and other artifacts illustrating the civic and religious life of the city. The museums also include Renaissance and Baroque paintings, as well as the richly frescoed walls of the Conservators' Apartment in the Palazzo dei Conservatori, which depict scenes from Rome's early history.

An equestrian statue is a statue of a rider mounted on a horse, from the Latin eques, meaning 'knight', deriving from equus, meaning 'horse'. 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.
