Michael Phelps has nothing on her: The French triathlete Léonie Periault, rising out of Guanabara Bay in Rio, is caught mid-lap, looming over the water, her wingspan stretching more than 98 feet.
Ms. Periault is not competing in the Olympics, but she is there, represented in black and white and surrounded by scaffolding, thanks to the French artist JR. Her image is one of three giant sculptures JR installed around the city, as one of the Olympics’ first artists in residence. The program, which began this year, was intended to “open up Olympism and its values to the widest possible audience,” according to a statement by the Olympic committee.
