Salvador Dali, “Corpus Hypercubus” (1954)
Dali depicts Jesus Christ crucified upon the cross – like 3D net of a tesseract or hypercube (one of the 261 distinct nets), the 4D analog of a cube. A hypercube, inhabiting a 4D space, casts “shadows” of a variety of three dimensional shapes upon 3D space and it can be formed by properly folding a 3D net consisting of eight cubes (though this kind of folding is far from possible to imagine), such as the one depicted in “Corpus Hypercubus”. From this point of view, Dali’s painting represents a pathway from 4D space (hypercube) towards 3D space (hypercube net) and then towards 2D space (the canvas surface). The event of Crucifixion appears to be taking place in Catalonia, with Port Lligat in the background while Dali’s wife, Gala, is looking up to the crucified, suspended in space Jesus.
