Edgar Degas
Degas's only showing of sculpture during his life took place in 1881 when he exhibited "The Little Dancer of Fourteen Years". A nearly life-size wax figure with real hair and dressed in a cloth tutu, it provoked a strong reaction from critics, most of whom found its realism extraordinary but denounced the dancer as ugly. In a review, J.-K. Huysmans wrote: "The terrible reality of this statuette evidently produces uneasiness in the spectators; all their notions about sculpture, about those cold inanimate whitenesses ... are here overturned. The fact is that with his first attempt Monsieur Degas has revolutionized the traditions of sculpture as he has long since shaken the conventions of painting."

The painting was begun in 1860 with Degas returning to the canvas to rework the piece over the following years, though it remained unfinished upon the artist's death. X-rays taken of the work during the early 21st century have revealed that Degas changed the positioning of the youths, their faces, and even their number; this last change resulted in the strange image of the four women in the foreground having ten legs among them. Degas' revisitation of the faces of the young people is often mentioned in art criticism, as it is believed the artist changed the features of the youths from the classic handsome Greek ideal, to a more urban modernistic look. The French art historian André Lemoisne, was first to note on this fact, remarking that the subjects had a contemporary Parisian look, more akin to the "gamins of Montmartre". More recent critics agree with Lemoisne, believing Degas was attempting to "update" his painting. 
A second full-scale version of the painting exists, held by the Art Institute of Chicago. This version is much less finished, but it shows a vastly different background, with a more detailed landscape and a large architectural structure, around which the characters in the background are resting. The work also shows how Degas changed the number of foreground figures with an additional boy on the right of the painting.
