Life and Monastic Foundation
Saint Dius was born in Antioch in Syria toward the end of the fourth century, into a pious Christian family, and from youth gave himself to severe asceticism, eating little and not every day and keeping constant vigil and prayer. The synaxarion relates that the Lord commanded him in a vision to go to Constantinople, there to serve both God and the people, and that he settled in a solitary place beyond the city which others feared to inhabit.
Emperor Theodosius the Younger is said to have come to him for a blessing together with Patriarch Atticus of Constantinople (406-425). The emperor funded the construction of a monastery, and the Patriarch ordained Dius to the priesthood and installed him as abbot (igumen). The people of the area came to him for counsel and guidance, and whatever was offered to him he distributed to the poor, the homeless, and the sick.
