Much of Augustine's later life was recorded by his friend Possidius, bishop of Calama (present-day Guelma, Algeria), in his Sancti Augustini Vita.
Kebanyakan kisah kehidupan selanjutnya Agustinus dibukukan oleh Possidius, yang adalah temannya dan uskup Calama (kini Guelma, Aljazair), dalam Sancti Augustini Vita karyanya.
