Otázka: Books – history of printed material
When writing systems were invented in ancient civilizations, stone, clay, tree bark (kůra), and metal sheets were used for writing. A tablet (deska) was the first robust writing medium. Clay tablets were used for writing in cuneiform (klínové písmo). Papyrus was used for writing in Ancient Egypt. Papyrus sheets glued together formed a scroll (závitek).
Later, wax tablets became the common writing materiál in schools and in accounting and for taking notes. They were reusable: the wax could be melted and reformed into a blank slate. During the Middle Ages the format of a codex (předchůdce knihy) became more economical, as both sides of the writing materiál could be used. It was portable and easy to hide. A book was much easier to read, the reader could find a page that he wanted, and could flip through (listovat) the pages.
