Stefanos, the eminent Athenian and the great ruler of Vigla, was tonsured a monk and became the Abbot of the Monastery. He managed to successfully act as an arbitrator on behalf of the Emperor Nikiforos Votaneiatos with the rebel Vasilaki in Thessaloniki, resulting in a very beneficial outcome for the Monastery. Among the important manuscripts and artefacts donated to the Monastery were the two portable mosaic icons of St Georgios and St Dimitrios, a fact supported by evidence and accepted today. The mosaics are the largest of their kind in the world, and are safeguarded in the sacristy of the Monastery.
