The elevated tetrahedron - fire - (a platonic figure of 12 triangles) measures 8.5" x 8.5”. De divina proportione. In 1509 Luca Paciola published this legendary book. Its illustrator, Leonardo da Vinci, devised a method to portray the five Platonic shapes in 3-D perspective, shaded like real objects, rather than geometrical diagrams. From Plato’s time these forms had special significance to mathematicians and philosophers alike, representing symbols for earth and fire, water and air.The juxtaposition of science and art intrigued Renaissance intelligentsia. Wooden models commissioned at Milanese and Florentine courts became actual symbols of learning and sophistication. Besides their metaphysical and geometric importance, the Da Vinci polyhedral shapes are quintessential building blocks of matter. From delicate pieces of wood, skilled craftspeople hand construct these fragile forms, truly resembling the beauty and harmony of nature’s perfection. This item is handmade with intricate hand crafted joints. It is finished in a translucent shade of distressed French finish honey. It comes complete with a story hangtag.
