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.
