The Harem in a Kiosk Jean-Léon Gérôme (1824-1904)

The picture has something of this: water, people, sea, outdoors, ocean, daylight, landscape, sky, architecture, resort, recreation, chair, dug-out pool, seashore, vacation.
Perhaps it’s a painting of a man with a sword in front of a gazebo next to a body of water with people on the other side of it.
