DODECAHEDRON (Gr.

Elie de Beaumont, in his speculations on the relation between the direction of mountain ranges and their geological age and character, was feeling towards a comprehensive theory of the forms of crustal relief; but his ideas were too geometrical, and his theory that the earth is a spheroid built up on a rhombic dodecahedron, the pentagonal faces of which determined the direction of mountain ranges, could not be proved.'

The great stellated dodecahedron is formed by stellating the faces of a great dodecahedron.

The "rhombic dodecahedron," one of the geometrical semiregular solids, is an important crystal form.
