An interdisciplinary approach to ancient and late antique commentaries reflects various MPIWG research initiatives on ancient commentaries, partly in cooperation with Topoi and the ERC project BabMed. While most of the research results from these seminars and workshops and events will appear in other publications, the present selection has important strands of coherence which will make this Preprint useful as a window into ancient commentaries. The texts discussed in this preprint extend from later phases in Mesopotamia hermeneutics to the broad reach of Greek and Byzantine scholarship, which also impacted Slavonic technical learning while en route back to Latin Europe via Arabic and Hebrew. The impression offered by these papers is one of familiarity of topics, as one generation of scholars were challenged to explain the intellectual heritage of their predecessors.
