Discovery of Michelangelo draft

On 7 December 2007, a fragment of a red chalk drawing of a section of the dome of the basilica, almost certainly by the hand of Michelangelo, was discovered in the Vatican archives. The drawing shows a small precisely drafted section of the plan of the entablature above two of the radial columns of the cupola drum. Michelangelo is known to have destroyed thousands of his drawings before his death. The rare survival of this example is probably due to its fragmentary state and the fact that detailed mathematical calculations had been made over the top of the drawing.
