Miguel de Cervantes — Portrait of Miguel de Cervantes Saavedra commonly said to be that which, according to the prologue to Cervantes' "Exemplary Novels", was painted by Juan de Jáuregui. Modern scholarship does not accept this, or any other graphic representation of Cervantes, to be authentic, nor is there any documentation for Jáuregui having painted this portrait.
