polyhedra and art  -  classical

This truncated icosahedron represented with "solid edges" is one of the illustrations of The Divine Proportion  (Lucas Pacioli).

The polyhedron on the top left of this portrait of Luca Pacioli is a glass small rhombicuboctahedron half-filled with water.

With its 8 faces (2 equilateral triangles and 6 symmetric pentagons), this polyhedron is a truncated rhombohedron: first stretch a cube along one diagonal, then cut the two peaks so that the remaining solid is inscribed in a sphere.

There are two ways to build this polyhedron:

• excavate twelve triangular prisms on a cube truncated at the third by the vertices (in red)
• augment a cube truncated by the edges and the vertices (in green) with eight flat triangular antiprisms
