Who's hand is that?
This is one of many hands that Rodin sculpted. We don't know whose it was modeled after, if anyone. Rodin was fascinated by the expressive qualities of gesture and often experimented with disembodied parts.
What is the meaning of the hands?
These hands are kind of like practice sculptures for larger works. Rodin was interested in expressing stories and emotion through the body. He would sculpt different body parts separately so that he could focus on one at a time. For example, the large hand on the left is based on the hand of a pianist. Also, Rodin took inspiration from ancient sculpture which is often found in fragments.
