The conquest of Ceuta completed, the elder princes devoted their extraordinary powers of mind and body to pursuits worthy of the cousins of Henry V. of England. Dom Edward, so named after his great-grandfather, Edward III. of England, the eldest son, married Donna Leonora of Aragon, and helped his father in the duties of government. He proved an apt pupil of João das Regras, the chancellor, and, after devoting much time to legal studies, he drew up the first code of Portuguese law. Dom Pedro, the next brother, who was created by his father Duke of Coimbra after the storming of Ceuta, travelled all over Europe, enjoying in turn the hospitality of Henry V. of England, of the Emperor, and of the Pope, and astonishing those monarchs by his abilities. He proved his valour by fighting beside the Teutonic knights against the Lithuanians, in the extreme east of civilised Europe, and his literary taste by his enlightened patronage of men of letters in all parts of the continent. In 1428 he ended his travels, and settling at Lisbon, he married Donna Isabel, the daughter of the Count of Urgel, and assisted his father and elder brother in the duties of government, taking special interest in the progress of literature, and co-operating in all the various schemes for the development of Portugal. The third brother, Dom Henry, created by his father, Duke of Viseu, and appointed Master of the Order of Christ, and governor of the kingdom of the Algarves, has left his mark on the history of the world as Prince Henry "the Navigator." This prince refused all the offers of the Pope, the Emperor, and of Henry V., to visit their courts, and established himself in 1418 at Sagre in order to devote himself and his wealth to the cause of discovering a continuous route by sea to India, which should bring the trade of Asia and its profits to the Portuguese. His efforts and the discoveries he superintended form the subject of a separate chapter, but it must be remembered that in all his efforts he was seconded by his father and elder brothers. The fourth brother, Dom John, Master of the Order of Santiago, married his niece Isabel, daughter of the Count of Barcellos, and became eventually third Constable of Portugal. The fifth brother, Dom Ferdinand, who earned the title of the "Constant Prince" in after years, was Master of the Order of S. Benedict of Aviz, as his father had been before his elevation to the throne; his piety was so well known, that he was requested to enter the Church, and promised a cardinal's hat by the Pope, but he refused the honour, longing rather for the glory of a crusader than the influence of an ecclesiastic, and winning in the end a martyr's crown. Their sister, Isabel, was as famous for her beauty, as her brothers for their valour, wisdom, and piety, and was married to Philip "the Good" of Burgundy, the founder of the Order of the Golden Fleece. To mar the unity of this illustrious and gifted family, there existed a half brother Affonso, the son of King John by Ines Pires, born before the marriage with Philippa of Lancaster, who was jealous of his legitimate brothers, and ultimately proved the evil genius of their destiny. This son was regarded with special favour by his father, who brought about his marriage with Donna Beatrice Pereira, daughter and heiress of the Holy Constable, and created him Count of Barcellos.
