DE PROMISSIONIBUS ET PRAEDICATIONIBUS DEI. - A work falsely attributed to Prospero d'Aquitania, although Cassiodoro already knew this authorial name (Institutiones divinarum litterarum: PL 70, 1111). From the context of the work it emerges that the author is not a Gaul, but a Carthaginian, who moved to Campania in the time of Pope Leone.
These circumstances of time and place support the attribution to Quodvultdeus, bishop of Carthage and exiled in Campania. The author speaks of 153 prophecies (according to the number of fish in Jo. 21,11) concerning Christ and the Church, showing that part of them has already been fulfilled and that the rest will be fulfilled in the future. The book is also important for the history of the Latin Bible.
BIBL.: Ed. in PL 51, 733-38. D. Franses, Die Werke des hl. Quodvultdeus (Veröffentlichungen aus dem hirchenhistorischen Seminar, 4ª serie, n. 9), Monaco 1920, p. 37 ff. (ibid., 45 ff. also on a difficulty concerning the attribution to Quodvultdeus). Perhaps Prospero revised the work. More recently A. D. Nock, in Vigiliae Christianiae, Amsterdam 1949, p. 54 f., expresses doubts regarding the identification. Erik Peterson
