For more than five centuries The Last Supper has been an artistic, religious and cultural icon. The art historian Kenneth Clark called it 'the keystone of European art,' and for a century after its creation it was regarded as nothing less than a miraculous image. And yet there is a very human story behind this artistic 'miracle.'  Until now, no one has told the full story behind its creation. Political events weighed on da Vinci and all of Italy during the time of the painting's conception and creation, as his patron, the Duke of Sforza, unleashed forces leading to a decades-long series of tragedies known as the Italian Wars. Sforza was overthrown by French forces in 1499, forcing da Vinci to flee Milan with the paint on The Last Supper barely dry. The Last Supper ensured Leonardo's universal renown as a visionary master of the arts. Ross King unveils dozens of stories that are embedded in the painting, and overturns many of the myths surrounding it. Bringing to life a fascinating period in European history, he presents an original portrait of one of history's greatest geniuses through the lens of his most famous work.
