and if u start to think..................

'The Last Supper' painting by Leonardo has been damaged and restored so much that it is difficult to ascertain precisely what the original looked like. Leonardo's first biographer, Vasari, writing in the 16th century decribed it as 'ruined' by the paint chemically reacting with the plaster ground and flaking off. It was heavily restored in the 18th century then later was vandalised by French soldiers. During WW2 the building was hit by a bomb. It was massively restored in the 1979 - 1999 so what you see today is mostly not Leonardo.
