A disciple of St Pachomius and great among the Egyptian ascetics, he was abbot of Tabennisi. He spent his whole life in absolute purity. One of the brethren once asked him: "What path leads to humility?" To this Tithoes replied: "The path to humility is, abstinence, prayer and the considering of oneself as the least of all creatures." He reached a very high peak of perfection and, whenever he raised his hands in prayer, his spirit entered into ecstasy. He entered into rest in the fourth or fifth century. Our Holy Father Ibistion is commemorated together with him.
