5. AEGYPTIUS (3). A monk of the Thebaid, celebrated for his supposed power of foretelling future events. The emperor Theodosius the Great, when preparing for his expedition against Eugenius (A. D. 393 or 394), sent the eunuch Eutropius to fetch Joannes to court, that the emperor might learn from him what would be the result of the expedition. Joannes refused to go with the eunuch ; but sent word to the emperor that he would gain the victory, but would soon after die in Italy.
