The sculpture was cast on
bronze with black, brown and green
patina. It has a 12.5 x 15.1 x 15.3 cm (3.1 x 3.8 x 3.8 in) base, where Rodin's signature can be found. Even though there is a clear influence by other works at the
Louvre, this mask represents the fidelity on contours that is characteristic of Rodin, made clear in the profound wrinkles and severe facial expression. This work was crucial in Rodin's unique aesthetical development. According to the artist himself: "That mask determined all my future work; it's the first modeled piece I did. Ever since, I've tried to see my works from all possible points of view and to draw them in every one of their aspects. That mask has been on my mind in every thing I have done". His later portraits have a singular life and individuality, partly because Rodin stayed on his contour modeling principles. == Problems ==
