Giovanni Antonio Amadeo was an Italian Renaissance sculptor of the Early Renaissance, architect, and engineer. He dominated late fifteenth-century Lombard architecture and sculpture.

Italian Renaissance sculpture was an important part of the art of the Italian Renaissance, in the early stages arguably representing the leading edge. The example of Ancient Roman sculpture hung very heavily over it, both in terms of style and the uses to which sculpture was put. In complete contrast to painting, there were many surviving Roman sculptures around Italy, above all in Rome, and new ones were being excavated all the time, and keenly collected. Apart from a handful of major figures, especially Michelangelo and Donatello, it is today less well-known than Italian Renaissance painting, but this was not the case at the time.
