Who really was Leonardo da Vinci? The author of the Cenacolo of the Monna Lisa and many other masterpieces, or the Antichrist? The man of faith or a heretic? Perhaps of all, maybe more. It depends on how you look. Here is the first volume of the trilogy, “Leonardo’s life 1°- The witches' sabbath." Tells, through the eyes of his disciples, the man wanted by Ludovico il Moro to help him realize his unbridled political ambitions of Europe. With his many qualities and many defects. Among alchemists in search of the Philosopher's Stone, witches engaged in demonic Sabbath, Inquisition burning at the stake not only witches, but all the classical works, books, statues or paintings. A horror that even today we live.
