ALL watermarks that are visible in the six choirbooks have been traced and are depicted below. Wherever possible references are made to similar marks that can be found in watermark reference works. It should be pointed out that for watermarks 11, 14, 15 and 19 only similar examples have been located on large (Royal) paper size; all other references are to watermarks on smaller sizes of paper (Chancery paper). Many of the Leiden watermarks contain a small cloverleaf – the so-called trefle – which is the symbol of the town of Troyes and, as of 1428, a common characteristic of paper that was produced there.
Unfortunately, the watermarks could not be reproduced in their original sizes. Therefore, each watermark is printed here with two numbers expressing (in millimetres) the height of the watermark figure (H), and the distance between the chainlines of the watermark at the centre position of its figure (W).
