[232] When Alexandra observed how things went, and that there were small hopes that she herself should escape the like treatment from Herod, she changed her behavior to quite the reverse of what might have been expected from her former boldness, and this after a very indecent manner; for out of her desire to show how entirely ignorant she was of the crimes laid against Mariamne, she leaped out of her place, and reproached her daughter in the hearing of all the people; and cried out that she had been an ill woman, and ungrateful to her husband, and that her punishment came justly upon her for such her insolent behavior, for that she had not made proper returns to him who had been their common benefactor. And when she had for some time acted after this hypocritical manner, and been so outrageous as to tear her hair, this indecent and dissembling behavior, as was to be expected, was greatly condemned by the rest of the spectators, as it was principally by the poor woman who was to suffer; for at the first she gave her not a word, nor was discomposed at her peevishness, and only looked at her, yet did she out of a greatness of soul discover her concern for her mother's offense, and especially for her exposing herself in a manner so unbecoming her; but as for herself, she went to her death with an unshaken firmness of mind, and without changing the color of her face, and thereby evidently discovered the nobility of her descent to the spectators, even in the last moments of her life.
