Genuine mix of sacred geometry, algebra, kabbalah and art.

There are several pictures that i recall from memory from time to time but the most remarkable from them is the masterpiece of Albrecht Dürer - Melencolia I. I like to meditate on that picture and it always gives me a new experiences and thoughts and charges with some creative powers. There so much patience and mystery in it. And look at this truncated trapezohedron. Isn't it perfect?
