Abba Dorotheus.

Saint Dorotheus was born in Gaza, in Palestine, and lived at the end of the 6^th and the beginning of the 7^th centuries. In his youth, he had learned many secular sciences and was well to do. He was in contact with the Elders Barsanuphius and John, and through their influence became a monk in the monastery of Abba Sveridus. Later he became abbot of a neighboring monastery. All his 21 instructions and some epistles have been preserved. He died in the year (circa) 620.
