Polymath:
http://en.wikipedia.org/wiki/PolymathThe dictionary definition is consistent with informal use, whereby someone very knowledgeable is described as a polymath when the term is used as a noun, or polymath or polymathic when used as adjectives. It especially means that the person's knowledge is not restricted to one subject area. The term is so rarely used that it is included in dictionaries of obscure words.[8][9]
Renaissance Man and (less commonly) Homo Universalis are related terms to describe a person who is well educated, or who excels, in a wide variety of subjects or fields.[10][11] This ideal developed in Renaissance Italy from the notion expressed by one of its most accomplished representatives, Leon Battista Alberti (1404�72): that �a man can do all things if he will�. It 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.
