• 60-sided die with faces numbered from 1 to 60.
• This design is based upon the geometry of the Pentagonal Hexecontahedron
• A variation of this design could be seen here: https://www.shapeways.com/model/150611/the_rosetta_dice__2__60_.html.

• Note: The unique construction method that I have used in assembling (piece by piece) this model is based upon a theorem on the duality of regular polyhedra that I have demonstrated in 1981 while creating and building by hand a series of polyhedral sculptures. For more info, see:
