Saint Niphon, Patriarch of Constantinople, was a native of Greece, and accepted monasticism at Epidauros. After the death of his Elder Anthony, he went to Athos, where he occupied himself by the copying of books. The saint was later chosen Metropolitan of Thessalonica, and still later occupied the Patriarchal throne in Constantinople and was primate of Valachia.
Banished under accusation, the saint went to Athos, at first to the Vaptopedi monastery, and then to the monastery of St John the Forerunner (Dionysiou). He concealed his rank and held the lowest position. By God's providence, his rank was revealed to the brethren of the monastery. Once, when the saint was returning from the forest where he had gone for firewood, all the brethren went out towards him on the way and solemnly greeted him as Patriarch. But even after this, the saint shared various tasks with the brethren. He died on August 11, 1460 at 90 years of age.
