So accurate was the examination of the divine words introduced by Origen, that he even thoroughly learned the Hebrew tongue, and made the original Scriptures, current among the Jews in the very Hebrew characters, his own possession; and he traced out the editions of the others besides the Seventy who had translated the sacred Scriptures, and discovered certain others, differing from the well-worn translations—those of Aquila and Symmachus and Theodotion—which, I know not whence, he traced out from certain recesses where they had long lain hidden, and brought to light.
Concerning these, because of their obscurity—not knowing whose they might be—he noted just this one thing only: that he found the one at Nicopolis near Actium, and the other in some such other place.
And indeed, in the Hexapla of the Psalms, after the four well-known editions, having set side by side not only a fifth but also a sixth and seventh interpretation, he has noted again concerning one of them that it was found at Jericho in a jar, in the times of Antoninus the son of Severus.
Having brought all these together in one, and divided them by clauses, and set them over against one another, together with the Hebrew notation itself, he has left us the copies of what are called the Hexapla; and separately he prepared the edition of Aquila and Symmachus and Theodotion together with that of the Seventy in the Tetrapla.
