An Italian secretary of the queen, Mary d'Medici, named Chalons, having retired to Rouen, advised Corneille to learn Spanish, and pointed out the "Cid" of Guillen de Castro as affording an admirable subject for a drama.[13] There are several old Spanish romances which narrate the history of the blow received by the father of the Cid from the Count Lozano--the death of the former by the youthful hand of the avenging son--and the subsequent demand which Ximena, daughter of Lozano, makes the king of the hand of Rodrigo. The Spanish poet saw that, by interweaving the idea of a prior attachment between Rodrigo and Ximena, the struggle of passion that must ensue, ere she could consent to marry the slayer of her father, presented a grand, deeply moving subject for a drama. Corneille followed closely in Guillen de Castro's steps: he rejected certain puerilities adopted by the Spaniard from the ancient ballads of their country, which were venerable in Spain, but might excite ridicule in France; but he at the same time injured his subject by too much attention to French rules. The senseless notion of unity of time takes away from the probability of the circumstances; and that which becomes natural after a lapse of years, is monstrous when crowded into twenty-four hours; so that we repeat Scuderi's exclamation, "How actively his personages were employed!" The French rule of having but two or three persons on the stage at a time detracts from the spirited scene, where, in the Spanish play, the nobles quarrel, and the blow is given at the council board of the sovereign. Corneille mentions one or two defects himself, which show rather his erroneous notions than defects in his play. Speaking of the weakness of purpose and want of power which the king displays as a fault, he says, no king ought to be introduced but as powerful and prudent; though he gives no reason why a dramatic sovereign should be an abstract idea, instead of an historic and real personage. When the king, in Guillen de Castro, shows himself as he was, the lord paramount of turbulent feudal nobles, whom he was unable to control, and yet to whom he will not yield, and exclaims---- "Rey soy mal obecido, Castigarè mis vasallos!"--
