Dancers Practicing at the Barre, dated 1877 and executed in mixed media on canvas, captures two ballet students at work rather than in performance, a choice consistent with Edgar Degas's broader interest in the discipline and labor behind the stage spectacle. The mixed technique — pigment applied with varying degrees of dilution and surface texture — reflects Degas's continual experimentation with materials during the 1870s, a decade in which he moved fluidly between oil, pastel, and combined media, often within a single picture. The canvas entered the collection through the H. O. Havemeyer bequest of 1929. Scion's advisory work draws on exactly this kind of technical specificity — medium, support, and condition — when assessing how a picture should be described, insured, and eventually valued.
