[478] Nay, Aristobulus had raised a quarrel between himself and Salome, who was his mother-in-law, besides the anger he had conceived at Glaphyra's reproaches; for he perpetually upbraided his wife with the meanness of her family, and complained, that as he had married a woman of a low family, so had his brother Alexander married one of royal blood. At this Salome's daughter wept, and told it her with this addition, that Alexander threatened the mothers of his other brethren, that when he should come to the crown, he would make them weave with their maidens, and would make those brothers of his country schoolmasters; and brake this jest upon them, that they had been very carefully instructed, to fit them for such an employment. Hereupon Salome could not contain her anger, but told all to Herod; nor could her testimony be suspected, since it was against her own son-in-law There was also another calumny that ran abroad and inflamed the king's mind; for he heard that these sons of his were perpetually speaking of their mother, and, among their lamentations for her, did not abstain from cursing him; and that when he made presents of any of Mariamne's garments to his later wives, these threatened that in a little time, instead of royal garments, they would clothe theft in no better than hair-cloth.
