In my lecture, I would first like to briefly introduce the academy project ‘Die alexandrinische und antiochenische Bibelexegese in der Spätantike’, its aims and the methods used in the production of the critical editions, as well as the workflows and tools we use in our editorial work. I will then offer insights into the text-critical findings of our project by means of two case studies: (1) on the reconstruction of the biblical lemmata in the Commentary on Psalms by Eusebius of Caesarea in the dynamic relationship of integral and fragmentary transmission, and (2) on the peculiarities of the New Testament text in the homilies of Severian of Gabala.
