Long after the statue was in its final form, he worked hours and hours and hours doing the fine detail work, days and weeks and months of tap, tap, tap with his hammer, sharpening chisels (that he made at a forge), sharper and finer until the Madonna's forehead was as smooth as glass. Michelangelo was 23 years old at the time, a real do-it-yourselfer.
Of course, the Sistine Chapel ceiling is also described in the book, and I was no less excited to see it. We took a long walk through the Vatican museums to reach the chapel, with tourists pushing in all on sides, and we were surprised to find the big chapel crowded with people, sardine-packed with people, many of whom had frightened looks (which will remain as my memory of the place, instead of the ceiling) as a big policeman screamed "Silenzio!" every few seconds from his perch on a table, like we were in some bizarre Italian horror movie in which a large lizard eats all the tourists.
Even with my glasses, the ceiling was too far away; the "Creation" was little more than a postage stamp. And Cheryl has an aversion to crowds, so we pushed our way through and out the door before the lizard got us.
