Renaissance Man

Leon Battista Alberti (1404–72). Architect, poet, musician, philosopher, linguist, cryptographer (founding father of western cryptography), painter and sculptor.

Renaissance man is an ideal that is epitomised by the notion of "a man can do all things if he will", which is expresses and championed by Leon Battista Alberti. The ideal embodied the basic tenets of Renaissance humanism, which considered man the centre of the universe, limitless in his capacities for development, and led to the notion that men should try to embrace all knowledge and develop their own capacities as fully as possible.

Thus the gifted men of the Renaissance sought to develop skills in all areas of knowledge, in physical development, in social accomplishments, and in the arts. The ideal was most brilliantly exemplified in Alberti himself, and in Leonardo Da Vinci.
