The queen declared her resolution of retreating into a convent at the expiration of six months; and she delayed thus long, merely to have an eye on the measures pursued by government. The favourite, dreading the exalted genius of this princess, and the natural influence of a mother over a son, prevailed on the king to treat her on several occasions with great disrespect, in order to hasten her retreat. The proud and haughty spirit of the queen could not submit to such indignities, and she retired immediately into a convent, where, perfectly convinced of the vanity of worldly grandeur, she passed her whole time in preparing for _that_, of which no human means could ever deprive her. She did not survive her departure from court quite a twelvemonth, dying on the 18th of February, 1660. This princess was possessed of a most superior genius: to the virtues of the softer sex, she added those by which the other is particularly distinguished. Seated on a throne, she displayed the splendid qualities of a great sovereign; and when retired into a convent, she seemed to have banished from her memory the regal diadem which had once graced her brow. The king, no longer restrained by the authority of this wise princess, gave way openly to the natural ferocity of his disposition, attacking by night, accompanied by his bravoes, every one he met, and even assailing the watch, and all others appointed to attend to the security of the city. Whenever he indulged himself in these nocturnal rambles, the next morning never failed bringing to light some tragical history, of which he was the hero; and the people felt as much dismayed on meeting him in the streets, as at the appearance of a savage beast escaped from his den. The count de Castello Melhor endeavoured to conceal excesses to which he owed his authority. A true courtier, though a weak unskilful minister; he was arrogant and proud when success crowned his wishes, but dismayed and helpless on a reverse of fortune. Portugal, thus governed, must inevitably have perished, had not the weakness of Spain secured its safety. The king, don Alphonso, whose authority did not extend beyond the walls of his palace, gave up the whole charge of the government to the care of his favourite, reserving no other part of the sovereign power, than the privilege of committing every species of extravagance with impunity.
