2009 marks another fundamental anniversaries in human knowledge: the 500th anniversary of the publication of De Divina Proportione, the art and mathematics treatise by Luca Pacioli and illustrated by Leonardo da Vinci.
De Divina Proportione was first published in Venice in 1509 . The golden ratio is one of the main themes, as the mathematical law representing the beauty and harmony of geometry found in nature. The Leonardo created drawings of the five Platonic solids, which were also later portrayed by Johannes Kepler in De Harmonices Mundi. The treatise is a celebration of the human desire of unification in knowledge by finding unity between the microcosm and macrocosm.
To celebrate this anniversary Axes Mundi Press has created the interactive DVD Polyhedra to be released in January 2010.
