Jerome. Lives of Illustrious Men 21
21 Agrippa Castor PL 23, 639
Agrippa surnamed Castor, a man of great learning, wrote a strong refutation of the twenty-four volumes which Basilides the heretic had written against the Gospel, disclosing all his mysteries and enumerating the prophets Barcabbas and Barchob and all the other barbarous names which terrify the hearers, and his most high God Abraxas, whose name was supposed to contain the year according to the reckoning of the Greeks. Basilides died at Alexandria in the reign of Hadrian, and from him the Gnostic sects arose. In this tempestuous time also, Cochebas leader of the Jewish faction put Christians to death with various tortures.
Agrippa, cognomento Castor, vir valde doctus, adversum viginti quatuor Basilidis haeretici volumina, quae in Evangelium confecerat, fortissime disseruit, prodens ejus universa mysteria, et prophetas enumerans, Barcaban et Barcob, et ad terrorem audientium alia quaedam barbara nomina: et Deum maximum ejus Abraxas, qui quasi annum continens, si juxta Graecorum numerum supputetur. Moratus est autem Basilides, a quo 863 Gnostici, in Alexandria temporibus Hadriani, qua tempestate et Cochebas dux Judaicae factionis, Christianos variis suppliciis enecavit.
Ἀγρίππας, ὁ ἐπίκλην Κάστωρ, ἀνὴρ πάνυ πεπαιδευμένος, κατὰ τῶν εἰκοσιτεσσάρων Βασιλείδου αἱρετικοῦ λόγων τῶν εἰς τὸ Εὐαγγέλιον παρ' αὐτοῦ περιφρασθέντων, γενναίως ἐξηγήσατο, πάντα αὐτοῦ τὰ μυστήρια ἐκφαίνων, καὶ τοὺς προφήτας συναπαριθμουμένους, Βαρκαβᾶν, καὶ Μαρκὸβ, καὶ πρὸς φόβον τῶν ἀκροωμένων, ἕτερά τινα βάρβαρα ὀνόματα, καὶ τὸν μέγιστον αὐτῷ θεὸν Ἀβραξὰς, οἷα ἐνιαυτὸν περιέχοντα κατὰ τὸν ἀριθμὸν τῶν Γραικῶν ψηφιζόμενον. Τελευτῶντος Βασιλείδου γνωστικοὶ ἐν Ἀλεξανδρείᾳ ἐκλήθησαν ἐν τοῖς χρόνοις 864 Ἀδριανοῦ, ὅτε καὶ Κόχιβος ὁ τῶν Ἰουδαίων ἡγούμενος πολλοὺς τῶν Χριστιανῶν ποικίλαις τιμωρίαις ἀνήλωσεν.
