The Platonic figures, the 'supreme expression of the majesty of geometry', were revered by philosophers and mathematicians of ancient Greece & the Renaissance. The mysterious powers of mathematics and science and its application to art were a favourite study of the quintessential Renaissance man, Leonardo Da Vinci (1452 - 1519). His delicately shaded polyhedrons appeared in Luca Pacioli's 1509 book De divina proportione. These shapes were thought to be related to the elements: the cube to Earth, Tetrahedron to fire, Octahedron to air, Iscosahedron to water and Dodecahedron to heavenly ether. Enjoy the classic beauty and pleasing proportions of the timelessly intriguing shapes.
