(1.) The wife of Zebedee and mother of James and John (Matthew 27:56), and probably the sister of Mary, the mother of our Lord (John 19:25). She sought for her sons places of honour in Christ's kingdom (Matthew 20:20, 21; Comp. 19:28). She witnessed the crucifixion (Mark 15:40), and was present with the other women at the sepulchre (Matthew 27:56).
(2.) "The daughter of Herodias," not named in the New Testament. On the occasion of the birthday festival held by Herod Antipas, who had married her mother Herodias, in the fortress of Machaerus, she "came in and danced, and pleased Herod" (Mark 6:14-29). John the Baptist, at that time a prisoner in the dungeons underneath the castle, was at her request beheaded by order of Herod, and his head given to the damsel in a charger, "and the damsel gave it to her mother," whose revengeful spirit was thus gratified. "A luxurious feast of the period" (says Farrar, Life of Christ) "was not regarded as complete unless it closed with some gross pantomimic representation; and doubtless Herod had adopted the evil fashion of his day. But he had not anticipated for his guests the rare luxury of seeing a princess, his own niece, a grand-daughter of Herod the Great and of Mariamne, a descendant, therefore, of Simon the high priest and the great line of Maccabean princes, a princess who afterwards became the wife of a tetrarch [Philip, tetrarch of Trachonitis] and the mother of a king, honouring them by degrading herself into a scenic dancer."

(1) One of the holy women who companied with Jesus in Galilee, and ministered to Him (Mark 15:40, 41). She was present at the crucifixion (Mark 15:40), and was among those who came to the tomb of Jesus on the resurrection morning (Mark 16:1, 2). Comparison with Matthew 27:56 clearly identifies her with the wife of Zebedee. It is she, therefore, whose ambitious request for her sons James and John is recorded in Matthew 20:20-24 Mark 10:35-40. From John 19:25 many infer that she was a sister of Mary, the mother of Jesus (thus Meyer, Luthardt, Alford); others (as Godet) dispute the inference.
(2) Salome was the name of the daughter of Herodias who danced before Herod, and obtained as reward the head of John the Baptist (Matthew 14:3-11 Mark 6:17-28; compare Josephus, Ant, XVIII, v, 4). She is not named in the Gospels.
