'The Memory Cathedral is the secret history of Leonardo da Vinci, adventurer, traveller, inventor, and lover of Lorenzo the Magnificent's mistress. Based on Leonardo′s own notebooks, this expansive, multi-layered novel is ostensibly about Leonardo′s flying machines. But it is really a magical exploration of the man, his drives, his loves, his friends, and fabulous inventions. It takes place in the Florence of Lorenzo de Medici and in the fabled, mythical east. Indeed, there is real evidence that Leonardo travelled to Egypt and Persia under the protection of the Devatdar of Syria, Lieutenant of the Sacred Sultan of Babylon. Imagine what would happen if Leonardo de Vinci had been given the chance to put his fabulous inventions to use - his bombs and machine guns and submarines and tanks and flying machines. Imagine Leonardo and a young Niccolo Machiavelli flying in a balloon over Egypt. Imagine Leonardo′s closest friend Sandro Botticelli being exorcised in Florence and riding through deserts with the Caliph of Egypt. Imagine living in the dangerous day to day world of the Renaissance and knowing intimately the greatest personages of the age. That is the experience of reading The Memory Cathedral'.
