Giambologna: Medici Horse - The Museum&#x27;s sculpture is based on a model by Giovanni Bologna, called Giambologna (Flemish, ca. 1529–1608) that was probably cast in the workshop of sculptor Giovanni Francesco Susini (Italian, ca. 1575–1653). Giambologna&#x27;s models were created for the equestrian statue of Grand Duke Cosimo I de&#x27; Medici in the Piazza della Signoria in Florence, which was finished in 1593.
