Ayala's nephew, FERNÁN PÉREZ DE GUZMÁN (1378-1460), continues his uncle's poetic tradition in the forms borrowed from Italy, as well as in earlier lyrics of the Galician school; but his mediocre performances as a poet are overshadowed by his brilliant exploit as a historian. He is responsible for the _Mar de Historias_ (The Sea of Histories), which consists of three divisions. The first deals with emperors and kings ranging from Alexander to King Arthur, from Charlemagne to Godfrey de Bouillon; the second treats of saints and sages, their lives and the books they wrote; and both are arrangements of some French version of Guido delle Colonne's _Mare Historiarum_. The third part, now known as the _Generaciones y Semblanzas_ (Generations and Likenesses), is Pérez de Guzmán's own workmanship. Foreign critics have compared him to Plutarch and to St. Simon; and, though the parallel seems dangerous, it can be maintained. This amounts to saying that Pérez de Guzmán is one of the greatest portrait-painters in the world; and that precisely he is. He argues from the seen to the unseen with a curious anticipation of modern psychological methods; and it forms an integral part of his plan to draw his personages with the audacity of truth. He does his share, and there they stand, living as our present-day acquaintances, and better known. Take a few figures at random from his gallery: Enrique de Villena, fat, short, and fair, a libidinous glutton, ever in the clouds, a dolt in practice, subtle of genius so that he came by all pure knowledge easily; Núñez de Guzmán, dissolute, of giant strength, curt of speech, a jovial roysterer; the King Enrique, grave-visaged, bitter-tongued, lonely, melancholy; Catherine of Lancaster, tall, fair, ruddy, wine-bibbing, ending in paralysis; the Constable López Dávalos, a self-made man, handsome, taking, gay, amiable, strong, a fighter, clever, prudent, but—as man must have some fault—cunning and given to astrology. With such portraits Pérez de Guzmán abounds. The picture costs him no effort: the man is seized in the act and delivered to you, with no waste of words, with no essential lacking, classified as a museum specimen, impartially but with a tendency to severity; and when Pérez de Guzmán has spoken, there is no more to say. He is a good hater, and lets you see it when he deals with courtiers, whom he regards with the true St. Simonian loathing for an upstart. But history has confirmed the substantial justice of his verdicts, and has thus shown that the artist in him was even stronger than the malignant partisan. It is saying much. And to his endowment of observation, intelligence, knowledge, and character, Pérez de Guzmán joins the perfect practice of that clear, energetic Castilian speech which his forebears bequeathed him.
