Flaming June is a painting by Sir Frederic Leighton, produced in 1895. Painted with oil paints on a 47-by-47-inch (1,200 mm × 1,200 mm) square canvas, it is widely considered to be Leighton's magnum opus, showing his classicist nature. It is thought that the woman portrayed alludes to the figures of sleeping nymphs and naiads the Greeks often sculpted.
Flaming June disappeared from view in the early 1900s and was rediscovered in the 1960s. It was auctioned shortly after, during a period of time known to be difficult for selling Victorian era paintings, where it failed to sell for its low reserve price of US$140 (the equivalent of $1,126 in modern prices). After the auction, it was promptly purchased by the Museo de Arte de Ponce in Ponce, Puerto Rico, where it currently resides.
