For a year and half, Rosa Bonheur dressed in mens clothes to avoid attention and wandered the Parisian horse market at the Boulevard de l’Hôpital. Her sketches informed The Horse Fair — a painting of such grand scale that Bonheur called it her “Parthenon frieze.” The Horse Fair was first shown in the Paris Salon in 1583, but Rosa reworked the painting for the next two years. 32 years later the painting would be aired by Cornelius Vanderbilt, who donated it to the Metropolitan Museum of Art.
Works in the public domain are those whose intellectual property rights have expired, have been forfeited, or are inapplicable. Artworks and writings enter the public domain when their copyright expires. Determining when a work's copyright expires is complex, but in general a work is in the public domain in the U.S. when it was created before 1923, and in most countries when the artist/author has been dead for 70 years. For these works, unlimited copy, distribution, modification, and reuse are allowed for free. More About Public Domain
