In the Greek study manuscripts of the Aristotelean tradition, the goal of combining and relating extensive core content and extensive para-content in such a way that constant interaction becomes possible, has been achieved in an exemplary manner. After introductory remarks on the complex and often multi-layered formatting of this type of manuscripts, a closer look is taken at the Organon codex Vat. gr. 244. The way in which Aristotle’s Analytica Posteriora are explained in this manuscript in large marginal commentaries is illustrated by the analysis of a sample passage.
