The Empire of Light is a series of paintings by René Magritte.
Via Daphne on Jim on Light:
Art is such a fantastic inspiration for us as lovers of light. That which is not lit cannot be seen, let alone painted, so these renditions of the world are our kin, and studying them can only benefit our work. This is a very theatrical piece, which shows how a tiny schism can create a spectacularly unsettling scene.
