It was Irving's intention, when he went to Madrid, merely to make a translation of some historical documents which were then appearing, edited by M. Navarrete, from the papers of Bishop Las Casas and the journals of Columbus, entitled "The Voyages of Columbus." But when he found that this publication, although it contained many documents, hitherto unknown, that threw much light on the discovery of the New World, was rather a rich mass of materials for a history than a history itself, and that he had access in Madrid libraries to great collections of Spanish colonial history, he changed his plan, and determined to write a Life of Columbus. His studies for this led him deep into the old chronicles and legends of Spain, and out of these, with his own travel and observation, came those books of mingled fables, sentiment, fact, and humor which are after all the most enduring fruits of his residence in Spain. Notwithstanding his absorption in literary pursuits, Irving was not denied the charm of domestic society, which was all his life his chief delight. The house he most frequented in Madrid was that of Mr. D'Oubril, the Russian Minister. In his charming household were Madame D'Oubril and her niece, Mademoiselle Antoinette Bollviller, and Prince Dolgorouki, a young _attaché_ of the legation. His letters to Prince Dolgorouki and to Mademoiselle Antoinette give a most lively and entertaining picture of his residence and travels in Spain. In one of them to the prince, who was temporarily absent from the city, we have glimpses of the happy hours, the happiest of all hours, passed in this refined family circle. Here is one that exhibits the still fresh romance in the heart of forty-four years:--
