A granddaughter of Herod the Great and Mariamne, daughter of Aristobulus, and sister of Herod Agrippa I. She was first married to her Uncle Herod Philip, but afterwards abandoned him and connected herself with his brother Herod Antipas. It was by her artifice that Herod was persuaded to cause John the Baptist to be put to death, she being enraged at John on account of his bold denunciation of the incestuous connection which subsisted between her and Herod. When Herod was banished to Lyons, she accompanied him, Matthew 14:3,6 Mark 6:17 Luke 3:19. See HEROD III.
