The Monk Galaktion of Belozersk was a student and cell-attendant of the monk Martinian of Belozersk and lived together with his mentor at the Ferapontov monastery.
The monk Galaktion cared with a filial love for the aged Abba Martinian. When his preceptor became completely infirm of body, the monk Galaktion took him to church on his shoulders. Beholding the spiritual maturity of his student, the monk Marinian blessed the monk Galaktion in his spiritual deed of folly. By his secret ascetic deeds blessed Galaktion reached high spiritual perfection, and obtained the grace of perspicacity. He foretold, that Kazan would be conquered by tsar Ivan, who was not yet even born. He foresaw his own end and the end of several of his fellow ascetics, and he also spoke of the fires and other disasters awaiting Ferapontov monastery. Blessed Galaktion died in the year 1506 and was buried at the foot of his teacher, the monk Martinian, at Ferapontov monastery.
