Father Toribio’s long personal intercourse with the Mexicans, and the knowledge of their language, which he was at much pains to acquire, opened to him all the sources of information respecting them and their institutions, which existed at the time of the Conquest. The results he carefully digested in the work so often cited in these pages, the _Historia de los Indios de Nueva-España_, making a volume of manuscript in folio. It is divided into three parts. 1. The religion, rites, and sacrifices of the Aztecs. 2. Their conversion to Christianity, and their manner of celebrating the festivals of the Church. 3. The genius and character of the nation, their chronology and astrology, together with notices of the principal cities and the staple productions of the country. Notwithstanding the methodical arrangement of the work, it is written in the rambling, unconnected manner of a commonplace-book, into which the author has thrown at random his notices of such matters as most interested him in his survey of the country. His own mission is ever before his eyes, and the immediate topic of discussion, of whatever nature it may be, is at once abandoned to exhibit an event or an anecdote that can illustrate his ecclesiastical labors. The most startling occurrences are recorded with all the credulous gravity which is so likely to win credit from the vulgar; and a stock of miracles is duly attested by the historian, of more than sufficient magnitude to supply the wants of the infant religious communities of New Spain.
