In the last decades of the 16th century, while directing the construction of a monastery sponsored by King Philip II of Spain, architect and humanist Juan de Herrera immersed himself in the theories of medieval Majorcan preacher and philosopher Ramon Llull. Herrera was looking for a universal epistemological construction, a figure that could serve as matrix for all existing knowledge. As a result of his research, he settled on the cube, producing a new theory of the geometrical figure that crossed historical boundaries and combined science and religion.
