This volume presents an edition of twenty-six drawings on papyrus and parchment from the holdings of the papyrus collections in Berlin and Vienna. Starting from previously published material of illuminated papyri, parchments and papers, this study is intended as a contribution to the discussion about the use of sketches and models in the visual arts. The actual edition catalogue of the twenty-six drawings is prefaced by an introduction reflecting on the definition of the terms "sketch" and "model" and commenting on the term "pattern book".
