What captures the observer's attention is the subtil reconstitution of what is occuring in the painting. The subject illustrates well René Magritte's concern with the relations between the visible world and the invisible one.

"What is hidden by the trees is here visible and the horse's tail remains concealed by a tree, in order to attribute to the phenomenon a less systematic description"

René Magritte
