Editor's note: One of history’s greatest artists, Michelangelo takes the cake for modesty: he rarely signed his work (the Pietà being a notable exception) and insisted that he was “not a painter.” The 25,000 people who cram into the Sistine Chapel daily to gawk at its ceiling will surely beg to differ! If you can’t get to Italy in the near future to admire his creations in person, tide yourself over with some exquisite Michelangelo wallpapers.
