David Foster Wallace’s INFINITE JEST was written (according to DFW) almost as a Sierpiński Gasket. The Sierpiński Gasket is a fractal and attractive fixed set named after the Polish mathematician Wacław Sierpiński who described it in 1915. However, similar patterns appear already in the 13th-century Cosmati mosaics in the cathedral of Anagni, Italy and other places, such as in the nave of the roman Basilica of Santa Maria in Cosmedin. Originally constructed as a curve, this is one of the basic examples of self-similar sets, i.e. it is a mathematically generated pattern that can be reproducible at any magnification or reduction.
