What is the processes that was used to create sculptures such as the Perseus by Benvenuto Cellini the David by Donatello and The Burghers of Calais by Auguste Rodin?

The sculptures "Perseus" by Benvenuto Cellini, "David" by Donatello, and "The Burghers of Calais" by Auguste Rodin were created through distinct processes reflective of their respective eras and styles. Cellini and Donatello primarily used the subtractive method, carving their forms from marble or bronze, emphasizing detailed anatomy and dynamic poses. Rodin, on the other hand, often employed a more expressive approach, using clay or plaster to model his figures before casting them in bronze, allowing for greater texture and emotional depth. Each artist's technique highlights their unique vision and the cultural context of their time.
