If the Royal Commentaries of the Incas, published in 1609, for a long time enjoyed an authority and exceptional prestige, if this work created the image in the French 18th century of an ideally ordered, just and virtuous society, it was no doubt due more to the admirable skill with which Garcilaso presented an especially brilliant and fascinating picture of the civilization of his maternal ancestors, the lords of Peru, than to the title of Inca, in which he could take pride—as the son of a Peruvian princess and a noble Spanish conqueror—or to the fact that he witnessed the aftermath of the conquest and the fall of the empire. It was perhaps a too attractive picture, and toward the middle of the 19th century it raised some doubt and scepticism. The Commentaries were then considered to be a romanticized history of the Inca civilization, even a utopia pure and simple. Modern criticism has reversed this view. It has pointed out that many facts in the book were valid, and that some were indisputable. Recent works tend to revindicate in their conclusions the historical importance and the sincerity of Garcilaso, without denying in the process the stylization, idealization and prejudices of the book. The viewpoint of the erudite Peruvian scholar Porras Barrenechea is in this respect significant: “The image of the Inca Empire that Garcilaso projects,” he writes, “is neither false nor deceptive. It is only one-sided. He gathered and related essentially favorable facts, those which exalted the memory of the lost empire and not which would have justified its disappearance…”
