Well, there is nothing in the dictionary on this, but I did find a reference in the Encyclopedia. Apparently, Maecenatism is a word that refers to private patronage of the arts... people who believe in being altruistic in support of cultural values. :) See this encylopedia article for more information about the man that the word was coined from (apparently he was a great patron of the arts and supported many young poets): http://www.reference.com/browse/wiki/Gaius_Maecenas
