impossible figure
Quick Summary
Impossible figures are drawings that appear to represent plausible three-dimensional objects but cannot exist in reality due to flawed perspective, false juxtaposition, or psychological distortion. These are also known as undecidable figures.1
Dutch graphic artist M.C. Escher was renowned for creating such works, combining meticulous realism with enigmatic optical illusions. His prints often depicted impossible architectural spaces and metamorphoses of objects. Examples include the Penrose square stairway, which seems to ascend or descend endlessly, and artworks like Escher's "Ascending and Descending" and "Waterfall". These figures are a type of optical illusion that challenges our perception of reality.213
