Chapter xviij: The Triumph of Evagrius
AND we also saw Evagrius, who was a man of great ability and learning, and who, through the experience of the matters which had passed over him, had acquired the discernment of good thoughts; and he had on several occasions gone down to the city of Alexandria and shut the mouths of the heathen philosophers. Now he commanded the brethren who were with us not to drink their fill of water, because devils were always to be found in the places where there were fountains of water, even according to the word of our Lord, Who said, “When the evil spirit hath gone forth from a man, it departeth and wandereth about in the places wherein there is no water seeking rest, which it findeth not” (St. Matthew 12, 43). And he spake unto us many things concerning the labours of ascetic excellence, and he confirmed our souls in the faith. Now many of the monks neither ate bread nor fruit (God forbid!), but bitter herbs and vegetables soaked in vinegar; and some of them never slept at all during the night, but, either sitting up or standing, they continued to pray until the morning.
