Wow! Michelangelo's Pieta is such a beautiful and touching piece of art.  I absolutely agree that this marble sculpture should be preserved for the future, because of it's realistic depiction of the Virgin Mary carrying her son, Jesus Christ, after his crucifixion.  It portrays so much emotion that appeals to the viewer.  I also think that it is incredible he had sculpted such a magnificent, detailed work with just one block of marble.  It's amazing how precise and accurate his image was solidified onto a life-like illustration of the passion and pain that the Virgin Mary had suffered.

Were all of Michelangelo's works religiously based?  Aside from his architecture, are there other works that Michelangelo has completed that is well known today and is not religiously referenced?
