manifest falsehood in the guise of hidden truth—stratagem and ruse—and your calling utter eradication and wholesale devastation “collection” and “rectification” for aims whose opportunities you grasped, snatching them from the claws of a valiant lion and the fangs of an awe-inspiring beast. Though you employ different words, you agree upon one meaning; and you are his stewards and confidants, so you bend his opinion to your desire (1) and blend your falsehood (2) with his truth, so he obeys you while you disobey him, and concurs with you while you oppose him.

At that time he was thirty-five (9) years, five months, and eleven days old, and he was among the most handsome of men and the most splendid in appearance, as the poet has said:
