The position of Calama is described by Augustine as between Constantine and Hippo, but nearer Hippo.—Contra Lit. Petil. ii. 228. A full description of it is given in Poujoulat's Histoire de S. Augustin, i. 340, who says it was one of the most important towns of Numidia, eighteen leagues south of Hippo, and represented by the modern Ghelma. It is to its bishop, Possidius, we owe the contemporary Life of Augustine.
