Available for prop rental or purchase; for pricing please inquire.

A geometric skeletal model of a dodecahedron so called “Platonic solid” for math and science study. It is made of connected ebonized wood elements (open in construction); this isĀ  similar in form to polyhedrons illustrated during the Renaissance by Leonardo da Vinci (1452-1519) for Luca Pacioli’s book The Divine Proportion (1509). Instead of drawing the solid with all its faces closed, Leonardo drew the illustrations in perspective as if constructed from structural frames, which allows the viewer to see inside and visually clarifies how the parts connect to each other and relate spatially.

Description

In geometry, a dodecahedron is a polyhedron with twelve flat faces. The most familiar is the regular Platonic solid dodecahedron. A Platonic solid is a three-dimensional polyhedron constructed by polygonal faces identical in size and shape, with all angles and sides equal, and with the same number of faces meeting at each vertex. The five Platonic solids include the tetrahedron (four faces), cube (six faces), octahedron (eight faces), dodecahedron (12 faces), and icosahedron (20 faces). They are named for the ancient Greek philosopher Plato who hypothesized that the classical elements were made of them. However, some sources credit Pythagoras with their discovery. Euclid described the Platonic solids in his ancient mathematical treatise, Elements. In the 16th century, the German astronomer Johannes Kepler attempted to relate the five known planets at the time to the five Platonic solids in Mysterium Cosmographicum, published in 1596.
