Note 340 — HISTORY OF GHARIB AND HIS BROTHER AJIB.[312]

Sapor the Second (A.D. 310–330) was compelled to attack the powerful Arab hordes of Oman, most of whom, like the Tayy, Aus and Khazraj, the Banu Nabhán and the Hináwi left Al-Yaman A.D. 100–170, and settled in the north and north-east of Al-Najd. This great exodus and dispersion of the tribes was caused, as has been said, by the bursting of the Dam of Márib originally built by Abd al-Shams Sabá, father of Himyar. These Yamanian races were plunged into poverty and roamed northwards, planting themselves amongst the Arabs of Ma’add son of Adnán. Hence the kingdom of Ghassan in Syria whose phylarchs under the Romans (i.e. Greek Emperors of Constantinople) controlled Palestine Tertia, the Arabs of Syria and Palestine; and the kingdom of Hírah, whose Lakhmite Princes, dependent upon Persia, managed the Arabs of the Euphrates, Oman and Al-Bahrayn. The Ma’addites still continued to occupy the central plateau of Arabia, a feature analogous with India “above the Ghauts.”
