Daws Dhú Tha‘labán, one of those who escaped from the massacre, fled to the Byzantine emperor and implored him, as the head of Christendom, to assist them in obtaining vengeance. Justinus accordingly wrote a letter to the Najáshí, desiring him to take action, and ere long an Abyssinian army, 70,000 strong, under the command of Aryáṭ, disembarked in Yemen. Dhú Nuwás could not count on the loyalty of the Ḥimyarite nobles; his troops melted away. "When he saw the fate that had befallen himself and his people, he turned to the sea and setting spurs to his horse, rode through the shallows until he reached the deep water. Then he plunged into the waves and nothing more of him was seen."[71] Thus died, or thus at any rate should have died, the last representative of the long line of Ḥimyarite kings. Henceforth Yemen appears in Pre-islamic history only as an Abyssinian dependency or as a Persian protectorate. The events now to be related form the prologue to a new drama in which South Arabia, so far from being the centre of interest, plays an almost insignificant rôle.[72] [Sidenote: Yemen under Abyssinian rule.] [Sidenote: Abraha and Aryáṭ.] [Sidenote: Abraha viceroy of Yemen.] On the death of Dhú Nuwás, the Abyssinian general Aryáṭ continued his march through Yemen. He slaughtered a third part of the males, laid waste a third part of the land, and sent a third part of the women and children to the Najáshí as slaves. Having reduced the Yemenites to submission and re-established order, he held the position of viceroy for several years. Then mutiny broke out in the Abyssinian army of occupation, and his authority was disputed by an officer, named Abraha. When the rivals faced each other, Abraha said to Aryáṭ: "What will it avail you to engage the Abyssinians in a civil war that will leave none of them alive? Fight it out with me, and let the troops follow the victor." His challenge being accepted, Abraha stepped forth. He was a short, fleshy man, compactly built, a devout Christian, while Aryáṭ was big, tall, and handsome. When the duel began, Aryáṭ thrust his spear with the intention of piercing Abraha's brain, but it glanced off his forehead, slitting his eyelid, nose, and lip--hence the name, _al-Ashram_, by which Abraha was afterwards known; and ere he could repeat the blow, a youth in Abraha's service, called ‘Atwada, who was seated on a hillock behind his master, sprang forward and dealt him a mortal wound. Thus Abraha found himself commander-in-chief of the Abyssinian army, but the Najáshí was enraged and swore not to rest until he set foot on the soil of Yemen and cut off the rebel's forelock. On hearing this, Abraha wrote to the Najáshí: "O King, Aryáṭ was thy servant even as I am. We quarrelled over thy command, both of us owing allegiance to thee, but I had more strength than he to command the Abyssinians and keep discipline and exert authority.
