Michelangelo sketch for St Peter's dome found

A sketch by Michelangelo for the dome of St Peter's Basilica, possibly his last design, has been found in the basilica's offices, the Vatican newspaper L'Osservatore Romano said. The drawing, for stonecutters working on the dome, was reportedly dated 1563, the year before his death. "The sureness in his stroke, the expert hand used to making decisions in front of unfinished stone, leave little doubt the sketch is Michelangelo's," the paper wrote. It said many drawings were destroyed by the artist, but this survived because a stonecutter used it to make notes about transporting stone into Rome.
