The first edition was printed by Mathias Clavijo in Seville in 1615; that is, two years after Torquemada had returned to Mexico, so his presence in Seville can only have been to select and arrange matters with the printer, and not to oversee the actual printing or check the galley-proofs. León-Portilla suggests these arrangements (including the choice of type and the layout) might have taken weeks at most, giving Torquemada time to visit Madrid and other places in the land of his birth. That no doubt explains how it happened that the first edition lacked two passages present in the manuscript, as well as words from some of the chapter headings, and contained countless other mistakes which the printer of the second edition noted but did not specify in his "Proemio". Despite the blemishes which marred the body of the first edition, the printer of the second edition was unstinting in his praise of the analytic indices which, he said, greatly enriched the text. According to a modern commentator, expressing also the hope that similar works would not omit a scientific apparatus of this kind, "their usefulness and erudition are formidable".
