Giorgio Vasari, Lives of the Most Excellent Painters… (1850)
“ No sooner had Francesco attained to some little height than he began to manifest his inclination to art, and before he had well taken the pen in hand to learn to write, he began to produce works in design. Impelled as he was by the force of Nature, which had destined him at his birth to be a painter, he began to do things, I say, which awakened surprise in all who beheld them. The master who taught him to write, perceiving this, and persuaded that the genius of the child must in time produce great results, advised his uncles to devote him to the study of design and painting. ”
