Which parts of a sculpture did Auguste Rodin usually create himself?

In his later career, Auguste Rodin functioned less as a traditional craftsman and more as an entrepreneur of sculpture, delegating much of the physical labor to assistants.1

Regarding the creation of his works, Rodin personally executed only the models. He would create many versions of these models while searching for the specific form that satisfied his vision.1

He consistently delegated the following tasks to others:
* Marble carving: He left the hewing of marble to assistants, who executed the work under his direction.12
* Bronze casting: This process was handled by specialists.1

By maintaining this "industrial" enterprise, Rodin was able to focus his own efforts on the initial conceptualization and modeling phases, while his assistants managed the technical execution of the final materials.12
