Marvel and Artefact examines the three surviving manuscripts of Wonders of the East (London, BL, Cotton Vitellius A. xv; London, BL, Cotton Tiberius B. v; and Oxford, Bodleian Library, Bodley 614). After outlining the learned tradition of writing on monsters and marvels and the family of texts of which the Wonders of the East is part, A. J. Ford offers a forensic reading of each manuscript in which codex, text and image are studied together as a single artefact. By focussing on the materiality of manuscripts whose origin can only be hypothesized, this innovative and challenging work opens new vistas for the study and interpretation of medieval manuscripts and the cultures that produced them.
