From the Economist:
Scientist, engineer, musician and great artist, Leonardo da Vinci is the archetypal Renaissance man. This undisputed genius, who lived to be 67, was also one of history’s most accomplished underachievers. He started many projects he did not finish; he accepted commissions he never began; his many planned treatises remained just notes. Only 18 of his paintings survive.
The artist was born near Florence in 1452 and went to Milan at the age of 30.
Intitally a painter, towards end of life he became a scientist. His works show a questing, never satisfied mind.
