The first law for the historian is that he shall never dare utter an untruth. The second is that he shall suppress nothing that is true. Moreover, there shall be no suspicion of partiality in his writing, or of malice.
Things sacred should not only be touched with the hands, but unviolated in thought.
[Lat., Res sacros non modo manibus attingi, sed ne cogitatione quidem violari fas fuit.]
