12. VICARIUS AFRICAE. Macedonius, who held the office of Vicarius Africae, in the early part of the fifth century, was the friend and correspondent of Augustin, who has described him as a person of many eminent qualifications. Two of his letters to Augustin, with Augustin's replies, are given in the works of that father. (Augustin. Epistolae, li.--liv. editt. vett., clii.--clv. ed. Caillau.)
