The Supposed Autographa of John the Scot

The author reevaluates the attribution of marginal notes and expansions in medieval manuscripts of De Divisione Naturae, testing a prior claim that they represent the author's own handwriting. By comparing hands across several codices and tracing patterns of correction and collaboration, he identifies multiple scribal and corrective hands, two distinct varieties of Insular script, and copying errors and variant readings that are inconsistent with a single authorial autograph. He concludes that the marginal additions cannot confidently be ascribed to the author and that the true autograph has not been located.
