De Viris Illustribus (Illustrious Men)

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.
