Crespi relates that Pietro Galletti, misled by a pleasing self-delusion
that he was born a painter, made himself the butt and ridicule of all
the artists of Bologna. When they extolled his works and called him the
greatest painter in the world, he took their irony for truth, and
strutted with greater self-complacency. On one occasion, the students
assembled with great pomp and ceremony, and solemnly invested him with
the degree of _Doctor of Painting_.
