In 1854 Gustave Courbet sent his patron and friend the rich philanthropist Alfred Bruyas a self-portrait, accompanying it with a letter:
It is the portrait of a fanatic, an ascetic. It is the portrait of a man who, disillusioned by the nonsense that made up his education, seeks to live by his own principles. I have done a good many self-portraits in my life, as my attitude gradually changed. One could say that I have written my autobiography.
This statement was somewhat premature (he was only forty-five at the time), but it is true that he was fascinated by his own appearance and some twenty self-portraits are extant. In the 1860s, when Emile Zola was trying to sum up Courbet’s achievement, he wrote that he saw him as “simply a personality.” Certainly Courbet made much of his own personality, and the revolution that he effected owed more than a little to the vividness of his presence and to the myth that he very soon succeeded in building up around himself.
