The founder of the dynasty of Avis, KING JOÃO I (1365-1433), found time in his busy reign of forty-eight years to encourage literature, ardently assisted no doubt by English Queen Philippa, and was himself an author. His keen practical spirit turned to Portuguese prose, and while as a poet he confined himself to a few prayers and psalms, in prose he caused to be translated the Hours of the Virgin and the greater part of the New Testament, as well as foreign works such as John Gower’s _Confessio Amantis_ (_c._ 1383), and himself wrote a long treatise on the chase. This _Livro da Montaria_, which has little but the title in common with Alfonso XI’s _Libro de Montería_, lay unpublished for four centuries, but is now available in a scholarly edition by Dr. Esteves Pereira from the manuscript in the Lisbon Biblioteca Nacional. Valuable and interesting in itself, this book is of great significance in Portuguese literature by reason of the impulse thus given to Portuguese prose. It is impossible as yet to estimate the full value of the prose works that followed: many are lost, others remain in manuscript, as the _Orto do Sposo_ by Frei Hermenegildo de Tancos, or the _Livro das Aves_. But with King João’s son and successor Portuguese prose came into its kingdom. Punctilious and affectionate, gifted with many virtues and graces, the half-English KING DUARTE (1391-1438), _o Eloquente_, shared the high ideals of all the sons of João I. Liable to fits of melancholy, and of less active disposition than his brothers Henrique and Pedro, he proved himself not less gallant in action than they at the taking of Ceuta in 1415, and had even earlier been entrusted by his father with affairs of State. His scruples as philosopher-or rather student-king during his unhappy reign of five years may have hampered his decisions, but his love of truth made the saying _palavra de rei_ proverbial. The corroding cares of State prevented him from giving all the time he would have wished to literary studies, but he was a methodical collector of books[190] and papers written by himself and others, and his great work, _Leal Conselheiro_ (_c._ 1430), consisted of such a collection on moral philosophy and practical conduct, addressed to his wife, Queen Lianor. It contains 102 chapters, often stray papers, sometimes translated from other authors.[191] Besides a detailed consideration of virtues and vices which are treated with an Aristotelian precision, and always with preference for the Portuguese as opposed to the latinized word, it has chapters on the art of translation, food, chapel services, and other subjects.[192] The book reveals a character of rare charm, combining humility with a clear instinct for what was right, humanity with common sense. His literary genius was akin to that of his father; he scarcely possessed poetical talent, although he translated in verse the Latin hymn _Juste Judex_, and possessed in his library a _Livro das Trovas del Rei_, in all
