"The term ''Bohemian'' has come to be very commonly accepted in our day as the description of a certain kind of literary gipsey, no matter in what language he speaks, or what city he inhabits .... A Bohemian is simply an artist or littйrateur who, consciously or unconsciously, secedes from conventionality in life and in art." (Westminster Review, 1862, noted at http://www.etymonline.com/b5etym.htm)
