Diocles

Venerable Diocles, also called Abba Diocles, studied grammar and philosophy, and at the age of twenty-⁠eight became a hermit in a cave. The synaxarion mentions him in connection with Heraclides, the author of the Lausaic History, who met him and asked him, among other things: "How is it possible, father, for the human mind to be always on divine thoughts?" The venerable answered: "As a person grows accustomed, whether with good thoughts or evil reasonings, so he conducts himself."

He is commemorated on 19 July in the calendar of the Church of Greece (new style), together with Venerable Dius. Other details of his life are not preserved in the sources consulted.
