The watering can, visible at left, was a standard fixture in ballet rehearsal rooms; water was sprinkled on the floor to keep dust from rising when ballerinas danced. Degas also used the watering can as a visual pun: its shape is mimicked by that of the dancer at right. Shown at the 1877 Impressionist exhibition, the painting was given by Degas to the collector Henri Rouart as a replacement for an earlier work (now lost), which the artist altered and accidentally destroyed.
Have a great new week! :)
P.S. See Dega's most beautiful ballerinas here <3
