His first marriage was to a sister of Mariamne I (wife of Herod) which marriage was allegedly arranged by Herod. When this wife died, Herod betrothed him to his eldest daughter by Mariamne I, Salampsio, but because of an affection for a "slave girl", by whose "charms" he was "overcome"[1], he rejected the marriage. Some time later Herod asked him to marry Salampsio's younger sister Cypros, and at first Pheroras agreed, but later he again refused and stayed married to his wife, who was very unpopular with Herod, and was involved in several plots against him.[2] [3]
