The collection of Aztec MSS., if not perfectly complete, is very extensive, and reflects great credit on the diligence and research of the compiler. It strikes one as strange, however, that not a single document should have been drawn from Spain. Peter Martyr speaks of a number having been brought thither in his time. (De Insulis nuper Inventis, p. 368.) The Marquis Spineto examined one in the Escorial, being the same with the Mendoza Codex, and perhaps the original, since that at Oxford is but a copy. (Lectures, Lect. 7.) Mr. Waddilove, chaplain of the British embassy to Spain, gave a particular account of one to Dr. Robertson, which he saw in the same library and considered an Aztec calendar. Indeed, it is scarcely possible that the frequent voyagers to the New World should not have furnished the mother-country with abundant specimens of this most interesting feature of Aztec civilization. Nor should we fear that the present liberal government would seclude these treasures from the inspection of the scholar. Much cannot be said in favor of the arrangement of these codices. In some of them, as the Mendoza Codex, for example, the plates are not even numbered; and one who would study them by the corresponding interpretation must often bewilder himself in the maze of hieroglyphics, without a clue to guide him. Neither is there any attempt to enlighten us as to the positive value and authenticity of the respective documents, or even their previous history, beyond a barren reference to the particular library from which they have been borrowed. Little light, indeed, can be expected on these matters; but we have not that little. The defect of arrangement is chargeable on other parts of the work. Thus, for instance, the sixth book of Sahagun is transferred from the body of the history to which it belongs, to a preceding volume; while the grand hypothesis of his lordship, for which the work was concocted, is huddled into notes, hitched on random passages of the text, with a good deal less connection than the stories of Queen Scheherezade, in the “Arabian Nights,” and not quite so entertaining.
