Résumé :
Abstract Earlier scholarship faced a number of limitations in classifying catena manuscripts on the Acts of the Apostles. This study makes a comparison of exegetical scholia in selected text passages (Acts 2:1–16, 8:9–25, 28:19–31) in order to determine the different types of catena and how they relate to each other. This survey reveals the diversity of the tradition: some manuscripts are merely copies, which repeat the same text with only small variations, but others are unique and cannot be directly identified with a particular catena type. It is therefore necessary to expand the classification of catenae on Acts in the Clavis Patrum Graecorum so as to mark subdivisions within the individual types.
