He is honored as the founder of Orthodox monastic life in Russia. He was born in Chernigov province and tonsured at the Monastery of Esphigmenou on the Holy Mountain. His abbot sent him from Mt Athos to Kiev to establish the monastic life there in 1013, during the last years of Prince Vladimir's holy reign. He lived there as a hermit, slowly drawing to himself others who wished to share the ascetical life. In time, the brotherhood grew into the Kiev Caves Lavra. St Anthony refused to serve as abbot of the monastery; this task was taken up by St Theodosius (commemorated May 3). St Anthony continued to live as a cave-dwelling hermit and reposed in peace at the age of ninety.
