Since the founding of the Pantokratoros Monastery, a bibliographic workshop has operated in the tower, in close collaboration with the library. The niches in the walls where the copiers worked still survive. From the end of the 14th century, we know the names of the monk-scribes Ignatios, Dionysios, Gerasimos and Theoliptos, while David Raidestinos, an important interpreter of music manuscripts, and Kallistos are known from the first decades of the 15th century. A second period of the systematic operation of the bibliographic workshop began in the 16th century, when the coders Neilos, Sabbas, Pafnoutios and Michael worked there, while during the same time in the Pantocratorian kalyvi of St Basileios in Kapsala, the heiromonk Theofilos the Myrovlytis continued his bibliographic work. Despite the invention and dissemination of typography, the bibliographic workshop continued to work into the 19th century.
