Across the most diverse societies, the reuse of writing surfaces in contexts such as learning to write, note-taking, literary creation, and bookkeeping has been not only desirable but essential to optimising resources. In these contexts, it has been typical to use erasable media of various kinds – a practice which in turn has had important implications for palaeography, literary creation, and virtually every aspect related to writing. Manuscript cultures addressed the quest for rewritability through using permanently recyclable materials such as clay and wax tablets, special technologies such as erasable coatings, and ingenious strategies for reusing papyrus, parchment, paper, wood, and more. This volume systematically explores the fascinating intersection between the potential ephemerality of the written word and the reusability of its supports. It combines a theoretical framework on ‘rewritability’ with case studies on materials, related technologies and their interplay with competing techniques, spanning from ancient Mesopotamia to present-day Nigeria, from Egypt to Japan, from Greece and Rome to the Arab world. In doing so, the volume illuminates a crucial aspect of cultural history relevant to anyone studying the written word.
