One of Michelangelo's really famous sculptures was David. David was started in 1501 and finished in 1504. Four years is a very long time to work on a sculpture in my opinion . It stood at 4.34m/14 ft tall . David was basically a sculpture of a human man standing.
One of Michelangelo's really famous paintings was the Sistine Chapel. The Sistine Chapel was built between 1475 and 1483. It is a rectangular shape and is 40,93 meters long by 13,41meters wide. The Sistine Chapel is also 20,70 meters high.
It's roof is a flattened barrel vault with little side vaults over the centered windows.
