Saint Alypius of Thagaste and Saint Possidius of Calama
Saints Alypius and Possidius were two of Saint Augustine's dearest and closest friends, sharing his life, ideals, and goals. Alypius was a student of Saint Augustine's, who later witnessed and joined in Augustine's conversion to Christianity.
Alypius was born in the middle of the fourth century in Thagaste, a small town in the Roman province of Africa Proconsularis. He was a member of the aristocracy, and his parents were leading citizens in Thagaste. In conformity with his parents' desire he studied law, which he later practiced as an assessor in Milan.
Alypius first met Augustine while at school in Carthage. In the Confessions Augustine mentions that there was mutual admiration between the: "He studied under me again at Carthage and held me in high esteem, because I seemed to him good and learned, while I for my part was fond of him on account of his great nobility of character, which was unmistakable even before he reached mature years." Elsewhere in the Confessions Augustine refers to him as "the brother of my soul."
While at school in Cathage, Alypius heard of Augustine's rhetorical skills, but decided not to attend his classes because of a disagreement between his own father and Augustine. Eventually, however, Alypius did become Augustine's pupil, and was deeply influenced by his sincerity and honesty.
In 384, Alypius followed Augustine to Milan. Here Augustine had opened a school of rhetoric and the two soon fell prey to the skeptical Academicians. It was in this city also that the two friends listened to the powerful preaching of Saint Ambrose, bishop of Milan, and found guidance in their spiritual search. In one of the most famous scenes of the Confessions, Augustine tells of his soul's torment before his conversion; all the while his friend Alypius was by his side. They were both converted to Christianity and later that year of 386 returned to the hills of Milan at Cassiciacum where they prepared for baptism by Ambrose at the Easter Vigil, 25 April 387.
Following their reception into the Church, the two friends returned to Africa where Alypius helped Augustine establish the first monastery in North Africa, at their hometown of Thagaste. When Augustine was later made priest at Hippo, Alypius moved there with him, and became a member of the first monastic community Augustine founded there. In 394/395 Alypius became bishop of Thagaste. His death took place around the year 430.

Despite his departure from the monastic community at Hippo, Possidius kept in close contact with Augustine. The two monk-bishops were reconciles to frequent traveling, the one means -- aside from correspondence -- of keeping their friendship and ideals united. The two were often traveling companions on trips to bishops' conferences. In 411, Possidius, together with Augustine and Alypius, were selected to represent the 266 Catholic bishops at the great conference between Catholics and Donatists held at Carthage.
