This essay advances an interpretation of early Christian codex books, which goes beyond Catherine Pickstock’s critique of Jacques Derrida. Firstly, it summarizes Derrida’s deconstruction of Plato’s Phaedrus and introduces his understanding of writing as différance. Secondly, it outlines Pickstock’s After Writing in order to understand her emphasis upon the liturgical nature of platonic dialogue. It is here that an ambiguity emerges between writing and codex books in Pickstock’s account. In response, the insights of book historians such as Roger Chartier will (...) be brought to bear in order to understand the longer history of the codex, which sees the printing press as a continuation of the early transition from roll to codex in the second century of the Common Era. It has long been noted that Christians of this period were early and pervasive adopters of codex binding for their sacred literature. By summarizing the reasons why, it will be shown how the codex expressed early Christian religious concerns. (shrink)
