The term CODEX refers to a BOOK or a SCROLL. It is derived from the Latin word codex, which means 'block of wood split into pages'. Codexes were used in ancient times as a way to store and organize information. They were made from wooden boards covered with wax or parchment and bound together with leather straps. Scrolls were also used for this purpose, but they were made from papyrus or parchment and rolled up. Both codexes and scrolls were used to record important information such as laws, religious texts, and historical events.
