With the one I managed to find a solution for I could read the letters mostly, but the words were badly spaced. Some letters appeared to belong to words as there was no space while some words were broken up into what looked like separate smaller words because the words wrapped from one line to the next.
The Roman scroll was easy to read fortunately.
The 3659 scroll is somewhat of a bugger to decipher.
How many scrolls and books with legible print are there?
