Herodias
   (Matt. 14:3-11; Mark 6:17-28; Luke 3:19), the daughter of
   Aristobulus and Bernice. While residing at Rome with her husband
   Herod Philip I. and her daughter, Herod Antipas fell in with her
   during one of his journeys to that city. She consented to leave
   her husband and become his wife. Some time after, Herod met John
   the Baptist, who boldly declared the marriage to be unlawful.
   For this he was "cast into prison," in the castle probably of
   Machaerus (q.v.), and was there subsequently beheaded.
