Among the missionary religions Buddhism is the most ancient one. It is the only unity factor of the whole Asian continent and it has inspired an art of deep spirituality, become a fundamental part of the world heritage. The chosen editorial form, while keeping the allure of a great artbook, is that of an historical atlas: that means that together with the photography of monuments, also plans, reconstructions, pictures and an unpu-blished cartography has been inserted, among in the widest iconography summoned up so far for single work on Buddhist art.
