Anno salutis humane nonagesimonono supra millesimum quadringentesimum Ipso die celebritatis autoris cursu felici ad finem vsque perducta. The Summa de Veritate (Epitome of Truth) of St. Thomas Aquinas, the angelic and most illuminate doctor, by the distinguished professor of divine learning Theoderic of Susteren, a regent deeply versed of the famous Cologne Convent of the order of Preaching Friars, newly by assiduous study restored to a fruitful harmony, so by Hercules that it truly rejoices in the true title of Truth, and printed at Cologne by the efforts and at the expense of the prudent Heinrich Quentell, citizen of the same, in the year of man’s salvation 1499, has been brought with favorable course even unto completion on the very festival of its author. In all these books editors could have had no difficulties to deal with save those which arise when texts are copied and recopied with the inevitable introduction of small errors at every stage, and perhaps some even more dangerous attempts to correct those already made. But in one class of printing, that of liturgical books, in which absolute accuracy of text and punctuation was of supreme importance, the need for careful supervision was really very great,—so much so, indeed, that the great bulk of liturgical printing was entrusted to firms who made a specialty of it. It is not surprising, therefore, to find some special insistence on the editorial virtues of a missal-printer; and the colophon to the Salzburg Missal printed by Georg Stuchs at Nuremberg in 1498 is interesting for its detailed account of the system of punctuation.
