The first suggestion that early Philippine books may have been printed from wood-blocks occurred in Quetif and Echard's bibliography of Dominican writers printed at Paris in 1719. There, after listing eight works by Blancas de San Jose, they add: "He published all these in the Philippines with the help of a Chinese Christian using Chinese blocks, for in his day European typographers had not yet arrived in those islands, nor did they have types for their language." [25] This was an amazing suggestion, for as far as we know the bibliographers who made it had not actually seen the books; nor is it entirely true. The first two works listed are two books we know were printed typographically in 1610. The sixth is _De los mysterios del Rosario de nuestra Senora Tagalice_, the book referred to by Fernandez as having been printed in 1602, and generally accepted as being from movable type, although no copy has been discovered to prove it. And yet, it is not at all impossible that some time before 1602 Blancas de San Jose had some of his writings printed from blocks. In any event, the idea, later developed by Medina and Retana, that xylography was used before a real printing-press was established, may have come from this not wholly accurate note. For almost a hundred and fifty years no historian or bibliographer wrote anything to challenge the basic affirmations of Chirino, Fernandez and Aduarte. In the middle of the 18th century, Lorenzo Hervas y Panduro, [26] a Jesuit, was forced by the expulsion of the Jesuits from Spain to seek refuge in the Papal States, and took up residence at Cesena. There he began work on a tremendous universal history of the spiritual development of man, into which he wove the results of his philosophical, social and linguistic studies. These last were of particular importance, and Hervas is regarded as the true founder of the science of linguistics and comparative philology. In 1785 he published the eighteenth volume of his massive work, the _Origine, formazione, meccanismo, ed armonia degl' idiomi_, in which he printed a Tagalog Ave Maria as written in 1593, with the note: "The Ave Maria in the Tagalog of 1593 is to be read in the Tagalog-Spanish Doctrina Christiana which was printed in Tagalog and roman characters by the Dominican fathers in their printing-house at Manila in the year 1593." [27] In 1787 he finished his twenty-first volume, _Saggio pratico_, [28] which was another philological study, including the Pater Noster in over three hundred languages and dialects, among them Tagalog, again from the 1593 Doctrina. Here, then, is ample proof that a copy of this book was known to Hervas in 1785, and the only information which his loose transcription of the title failed to give was that the volume was "corrected by members of the orders," that it was printed with license, and that it was printed at San Gabriel.
