3 Your first question is most ably answered by Origen in his treatise on First Principles which, at the request of my friend Pammachius, I have recently translated. This task has occupied me so fully that I am unable to keep my word with you and must again postpone the sending my commentary on Daniel. Indeed, distinguished and devoted to me as Pammachius is, had he been alone in his request, I should have deferred it to another time, but, as it was, almost all our brothers at Rome urged the same demand declaring that many persons were in danger, and that some even accepted Origen's heretical teaching. I have found myself forced therefore to translate a book in which there is more of bad than of good, and to keep to this rule that I should neither add nor subtract but should preserve in Latin in its integrity the true sense of the Greek. You will be able to borrow a copy of my version from the aforesaid brother, though in your case the Greek will serve quite as well; neither should you, who can drink from the fountain head, turn to the muddy streamlets supplied by my poor wits.
