(Βαγαῖος).
1. A Persian nobleman, to whom was allotted the dangerous office of conveying the order of Dareius Hystaspis for the execution of Oroetes, the powerful and rebellious satrap of Lydia, about 520 B. C. On his arrival at Sardis, Bagaeus first ascertained the disposition of the satrap's guards by the delivery to them of several minor firmans from the king; and, when he saw that they received these with much reverence, he gave the order for the death of Oroetes, which was unhesitatingly obeyed. (Hdt. 3.128.)
