On June 2, Myriam Krutzsch, the papyrus conservator of the Berlin Papyrus Collection (Staatliche Museen zu Berlin SPK, Ägyptisches Museum und Papyrussammlung), visited the CoptOT team to give two inspiring lectures on the material aspects of papyrus manuscripts and methods of dating the papyrus material, followed by a practical guide how to use these observations on two examples, the early papyrus codices: the so-called 'Berolinus Gnosticus' (ÄMP, P. 8502), and the Akhmimic Proverbs (Berlin, Staatsbibliothek SPK, Berol. orient. oct. 987).
