Foundation of Dionysiou Monastery
The monastery Dionysios established lies in a steep, secluded part of the Athonite peninsula and is dedicated to Saint John the Baptist, the Forerunner. According to the synaxarion the foundation took place around 1375, and a chrysobull of September 1374 issued by Alexios III Komnenos of Trebizond, still held in the monastery's archives, attests to the imperial role in its establishment.
The emperor's patronage was secured in part through Dionysios's brother Theodosios, who served as a metropolitan in Trebizond. The synaxarion records that the emperor provided substantial sums for the construction, given as fifty somia together with a further grant of komminata. Dionysiou remains one of the twenty ruling monasteries of the Holy Mountain.
