Leather
The Jewish Talmud specifically required that the Scriptures should be copied
on the skins of animals, on leather. It is most certain, that the Old Testament
was written on leather. Rolls were made by sewing skins together that were from
3 to 100 feet or more in length. The text was written in columns perpendicular
to the roll. The rolls were 18-27 inches high and rolled on one or two sticks.
