14. ANTIOCHENUS (6). The Excerpta ex Collectaneis Constantini Augusti Porphyrogeniti, περὶ ἀρετῆς καὶ κακίας, De Virtute et Vitio, edited by Valesius, 4to. Paris, 1634, and frequently cited as the Excerpta Peiresciana, contain extracts from the Ἱστορία Χρονικὴ ʼαπὸ Ἀδάμ, Historia Chronographica ab Adamo, of a writer called Joannes of Antioch, of whom nothing is known beyond what may be gathered from the work. The last extract relates to the emperor Phocas, whose character is described in the past tense, ὁ αὐτὸς Φωκᾶς ὑπῆρχεν αἱμοπότης, " This same Phocas was bloodthirsty :" from which it appears that the work was written after the death of Phocas, A. D. 610, and before the time of Constantine Porphyrogenitus, in the tenth century. Cave places Joannes of Antioch in A. D. 620. He is not to be confounded with Joannes Malalas, from whom he is in the Excerpta expressly distinguished. (Fabric. Bibl. Gr. vol. iii. p. 44, vol. viii. p. 7; Cave, Hist. Litt. vol. i. p. 577.)
