The exegetical texts on Aristotle\'s Organon form a very extensive chapter of logic and the didactics of logic in Byzantium. A common form of this commentary, in addition to \'running commentaries\' and individual scholia, are the numerous synopses and collections of definitions of terms, but also commentaries on individual passages of treatises of the Organon - these texts are usually transmitted anonymously. These are not only didactically orientated, canonical standard compendia of the theory of logic, but also texts that show a strong influence of Stoic logic and concern particular socio-cultural aspects of intellectual life in Byzantium. In this work, three such treatises and the accompanying diagrams are critically edited, annotated and translated into German.
