While not a painter himself, his profound theoretical work provided a framework for visualizing complex forms that deeply resonated with artists exploring abstraction and non-Euclidean spaces in the late 19th and early 20th centuries. His life was dedicated to unifying disparate branches of mathematics under elegant, ov…
