Renaissance art had solutions in angels and other flying creatures occupying areas needing foregrounding. Breughel used birds to good effect. Clouds were employed by Dutch landscape painters and Constable/Turner—the viewer taken into spatial recession along some canal path or other, but the journey back was on a cumulonimbus.
Late nineteenth century art freed paint from its full time job of representation so brushstrokes could take the place of objects. Artists started tilting landscapes, raising horizon lines so that land and picture became one, especially in works of Cezanne and Van Gogh. And from there on into various forms of abstraction. (In reverse, temporary apotheoses may occur when brushstrokes become flying creatures and spatial recession glimpsed in-between.)
