An English book which collects several contributions that cover the entire history of Milan, gravitating around some unitary reference centers and almost drawing a map of the genetic code of Milan. This is how the veins and arteries of that heart of Milan intertwine, which happily gives the title to this beautiful book. The lesson of the past allows you to cleave the mists of the present. And to look to the future without undue anxiety. Milan rediscovers the reasons for its economic and cultural leadership, together with the confidence in its capacity for moral leadership, in the very heart of its entire history.
