Under the roof of blue ionian weather Lawrence Alma-Tadema (1836-1912)

The picture has something of this: woman, architecture, outdoors, ancient, people, man, summer, sculpture, marble, stone, relaxation, antique, artistic, leisure.
Perhaps it’s a painting of a woman sitting on a wall next to a man and a woman standing in front of a staircase with a man on the other side of the wall.
