Heavily patinated boulders on wadi terraces in the Mahra Governate of Yemen reveal close connections to the Bronze Age of Southwestern Saudi Arabia (2500-1200 B.C.). The distinctive lunate pommeled daggers found on Bir Hima rock art (see above) can be paralleled on small boulder art in the Wadi Masilah complex, the wadis of Ghaydah al Mahrah, and the statue-menhirs of the eastern Yemen interior. These, in turn have close parallels to actual daggers found on Bahrain and at Ur (see above).
