What actual painting is this scene based on?
I think it’s a famous one I can’t bring to mind.
The Poussin has four figures (they could be the Seasons, or in Powell’s treatment the Kindly Ones, i.e. Furies), facing outward; while this scene has five, facing inward. The Poussin dates from 1634-1636, while this other scene with its contorted nudes surely is showing an influence of Impressionism or later.
Later: okay, I have been informed. It’s La Danse by Henri Matisse with versions from 1909 and 1910.
