Papyrus was used in ancient Gebal (Byblos) and Egypt from about 3100 B.C. It was made by pressing and gluing two layers of split papyrus reeds together in order to form a sheet. A series of papyrus sheets were joined together to form a scroll. It is that type of papyrus scroll that is mentioned in Revelation Rev. 5:1+ (though it is translated book in NASB). The apostle John used papyrus for his epistles (cf. 2 John 2Jn. 1:12).1
