Doubling the cube

Doubling the cube is a sculptural approach to the Delian problem, also known as one of the classic problems of ancient Greek mathematics.
According to legend, the oracle at Delphi instructed the citizens of Delos to build a new altar of twice the old altar’s volume and with the same cubic shape, using a compass and straightedge construction. The unsolvability of this task was proven only decades later since it requires algebraic means. In the early 20^th century, however, it was discovered that the problem of duplication of the cube could also be solved by folding paper. In its formal structure, the sculpture Doubling the cube refers to the cube as a three-dimensional geometric object as well as to paper folding as a geometric discipline.
