He is venerated as a saint who introduced the notion of a strict ascetic life to the Georgian Church.[2]
He was born in Antioch. At the age of 20, he became a disciple of the famous hermit John of Zedazeni,[3] distributed his property to peasants and monasteries, and became a monk himself.[4] In the middle of the 6th century, he lived in Mtskheta.
