An exception to this is provided by Falk 2014 who has surveyed all the prayer manuscripts from Qumran and part of the psalm manuscripts with an emphasis on their material features, including script size and line division. He excludes from his study the manuscripts containing now biblical psalms and the most fragmentary of the psalm and prayer manuscripts. Falk does make some observations on readability on a couple of occasions, but his main concern is the general size and quality of the different scrolls that relate, for instance, to their portability and considerations of economy. 3 The measurements given in this article are based on information given by the editors of the individual manuscripts in the official DJD editions that I have double-checked, and when this information is lacking, on my own calculations.
