Spanish poet, moralist, and historian, author of the first important work of history and historiography in Spanish. His historical portraits of his contemporaries earned him the title of the “Spanish Plutarch.”

A member of a distinguished family, Pérez de Guzmán devoted himself to letters after being imprisoned by Alvaro de Luna, a counselor to King John II of Castile. Although his poetry went through many editions, it is not as a poet that he is chiefly remembered. His fame rests on his Mar de historias (1512; “Sea of Histories”), a collection of biographies of emperors, philosophers, and saints, and primarily on the third part of this collection, which contains historical portraits of 33 prominent men and one woman from the reigns of Henry III to John II (the period 1390 to 1454). He knew many of the people whom he described, and, although the portraits are based on rhetorical models, the prose is clear and economical, capturing each personality in a few pages.

Equally important is the preface to the third part of the Mar, in which Pérez de Guzmán provided the first examination in Spanish of the theory of history and the responsibility of the historian, concerning himself with the problems of historical accuracy, the proper prose for a historian, and the problem of fame as a moral force in history.
