In the present context that fact might not appear particularly important. After all, the literary products of earlier centuries, too, are often preserved in manuscripts of much more recent date. But unfortunately the texts of the rederijkers which have been handed down from the 16th and early 17th centuries contain very little information concerning the date of origin. Neither does dating on the grounds of style or language help us here, because the material is extremely homogeneous in this respect. With a few exceptions, the fifteenth-century plays which are presumably present in the voluminous corpus of surviving manuscripts and printed editions cannot be identified as such. In the case of printed editions, it can usually be shown that the writing of the play and the year of publication are either close together or coincide, but in the case of manuscripts the year in which a work was copied out, or the date in which the paper was made, may be the only ascertainable fact. Since a large number of plays have been transmitted in copies dating from about 1600, there is clearly a fair amount of room for speculation.
When one has to collect the texts of the rederijker plays, this situation does at least have one advantage, and that is that it is not difficult to draw the borderline of rederijker drama at the fifteenth-century end: I included only manuscripts and books written or printed after 1500. At the opposite end, in the 17th century, the line is much more difficult to trace. The influence of the Renaissance does not really make itself manifest until after 1600, but the speed with which this occurs differs according as one is at a smaller or greater distance from the cultural centres, particularly Amsterdam. This also has consequences for the form in which plays have survived. Modern plays are written first and foremost in the cultural centres where they are then printed. Old-fashioned plays, even some that can with certainty be dated as 16th-century, were still being bought, sold, performed, and copied in such far-flung corners of the country as 's-Gravenpolder, a village of a couple of hundred inhabitants in the province of Zeeland, as late as the eighteenth century.
When compiling my Repertorium van het rederijkersdrama I took account of this difference in tempo and the consequent difference between plays in print and those in manuscript form, by excluding printed plays, and including manuscript ones, dating from later than 1620. When sorting them out I started from the overall impression which a play made upon me, and as regards the printed material I included as many borderline cases as possible. On the basis of the Repertorium I today count 274 printed and 365 manuscript texts surviving. Of the total of 639, the forty-six plays of which a second version has also been preserved must be discounted, so that the total number of plays is 593.
I hasten to reduce my statement to more manageable proportions. In the first place, there are the borderline cases mentioned
