michelangelo and Da Vinci

As you may know Da Vinci and Michelangelo were rivals. Da Vinci was kind of jealous of Michelangelo and often berated sculpture as as an art form. He felt that painting was superior because you cant control how light falls on a sculpture as ones chooses a light source in painting. Da Vinci was a bastard child and did not have a noble name as did Michelangelo Buonorrati. Michelangelo was proud of having a name of noble lineage and tried often to keep his wayward brothers and cousins in line as not to damage the family name. Da Vinci felt a bit of a stigma because his name Da Vinci only met where his was from ( the town of Vinci) I believe a large part of his life was a compensating factor to make his name into something noble. The average life span was just over forty in the renaissance and both Michelangelo and Leonardo lived well past the expected life span for their time. I think Michelangelo actually made it into his late 80's or even 90.
