Evagrius Ponticus

Evagrius Ponticus (Greek: Εὐάγριος ὁ Ποντικός, "Evagrius of Pontus"), also called Evagrius the Solitary (345-399 AD) was a Christian monk and ascetic. One of the rising stars in the late fourth century church, he was well known as a keen thinker, a polished speaker, and a gifted writer. He left a promising ecclesiastical career in Constantinople, traveled to Jerusalem, and there in 383 became a monk at the monastery of Rufinus and Melania the Elder. He then went to Egypt and spent the remaining years of his life in Nitria and Kellia, marked by years of asceticism and writing. He was a disciple of several influential contemporary church leaders, including Basil of Caesarea, Gregory of Nazianzus, and Macarius of Egypt. He was teacher of others, including John Cassian and Palladius.
