We know little as to how he passed his time. Probably he shared the studies of prince Duarte, who collected a large library and himself wrote a book of philosophical maxims, which gained him the surname of Duarte the Eloquent. The two brothers were bound together by the same tastes, and we may be sure Duarte approved when by-and-by Fernando refused the pope's offer of a cardinal's hat, on the ground--unheard of at that period--that, not being a priest, he was quite unfitted to wear it. For the same reason, though the cases were rather different, he wished also to refuse the office of grand master of the order of Aviz, which had been held by his father; but in the end Duarte's counsels prevailed, and he kept it. * * * * * Fernando was thirty years old when his father died, and never yet had his sword left its sheath, though he longed from his soul to join in the frequent expeditions that went out from Ceuta to attack the strongholds of the unbelievers scattered about the coast. But king John always refused to let him leave the country, thinking he was too delicate to bear the hardships of a soldier's life; and so Fernando stayed at home, making himself as happy as he could with his books and his prayers, and long philosophical talks with Duarte. Now Duarte was king, and perhaps Fernando would be able to gain his heart's desire. The new king was putting on his robes for the ceremony of his proclamation when his physician craved humbly an immediate audience. Dom Duarte wondered what could have happened which made an interview so necessary at that inconvenient moment, but master Guedelha was an old friend, so orders were given to admit him at once. 'Oh, senhor,' exclaimed the physician, as soon as they were alone, 'do not, I beseech you, suffer yourself to be proclaimed before noon; the hour you have fixed on is an evil one, and the stars which rule it are against you.' Sad though he was, dom Duarte could hardly help smiling at the earnestness of the man; but he answered gravely that, greatly as he respected the knowledge of the stars, his faith in God was greater still, and nothing could befall him that was contrary to His will. In vain Guedelha fell on his knees and implored him to delay till the fatal hour was past; Duarte refused to change his plans, and at length the old man rose to his feet. [Illustration: In vain Guedelha implored him to wait till the fatal hour was past.] 'I have done all I could,' he said; 'on your own head be it. The years of your reign will be short and full of trouble to yourself, and to those you love, and to the country.'
