Reutersvärd pioneered impossible figures and paradoxical geometric constructions in printmaking, earning him the title father of impossible art. His meticulous draftsmanship and fascination with architecturally inspired structures that defy spatial logic mirror the impossible suspended castle Escher rendered here.

Hughes specializes in impossible architectural spaces and optical illusions rendered with precise technical skill, creating works where perspective and spatial logic are deliberately subverted. His ongoing exploration of buildings and structures that simultaneously occupy contradictory spatial positions aligns directly with the suspended impossible architecture in this Escher piece.
