Returning to his homeland of Cappadocia, Gregory once again resumed his position as bishop of Nazianzus. He spent the next year combating the local Apollinarian heretics and struggling with periodic illness. He also began composing "De Vita Sua", his autobiographical poem. By the end of 383 he found his health too feeble to cope with episcopal duties. Gregory established Eulalius as bishop of Nazianzus and then withdrew into the solitude of Arianzum. After enjoying six peaceful years in retirement at his family estate, he died on 25 January in 390.
