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 littérateur who, consciously or unconsciously, secedes from conventionality in life and in art. [“Westminster Review,” 1862]
