This painting depicts Wittenham Clumps, an ancient British camp in Berkshire. The Clumps can be seen in the background; they are two dome-shaped hills with a thick clump of trees on top. Nash had been familiar with the area for many years, since spending family holidays nearby from 1909. He painted the Clumps in a series of dream-like works, three of which present the vernal (or spring) equinox, with the sun and moon depicted simultaneously in the sky. These paintings were intended as poetic metaphors, referring to the mystery and magic of the perpetual cycles of nature.
