Legend makes As‘ad the hero of a brilliant expedition to Persia, where he defeated the general sent against him by the Arsacids, and penetrated to the Caspian Sea. On his way home he marched through the Ḥijáz, and having learned that his son, whom he left behind in Medína, had been treacherously murdered, he resolved to take a terrible vengeance on the people of that city.

"Now while the Tubba‘ was carrying on war against them, there came to him two Jewish Rabbins of the Banú Qurayẓa, men deep in knowledge, who when they heard that he wished to destroy the city and its people, said to him: 'O King, forbear! Verily, if thou wilt accept nothing save that which thou desirest, an intervention will be made betwixt thee and the city, and we are As‘ad Kámil and the two Rabbins of Medína. not sure but that sudden chastisement may befall thee.' 'Why so?' he asked. They answered: ''Tis the place of refuge of a prophet who in the after time shall go forth from the sacred territory of Quraysh: it shall be his abode and his home.' So the king refrained himself, for he saw that those two had a particular knowledge, and he was pleased with what they told him. On departing from Medína he followed them in their religion.62 ... And he turned his face towards Mecca, that being his way to Yemen, and when he was between As‘ad Kámil at Mecca. ‘Usfán and Amaj some Hudhalites came to him and said: 'O King, shall we not guide thee to a house of ancient treasure which the kings before thee neglected, wherein are pearls and emeralds and chrysolites and gold and silver?' He said, 'Yea.' They said: 'It is a temple at Mecca which those who belong to it worship and in which they pray.' Now the Hudhalites wished to destroy him thereby, knowing that destruction awaited the king who should seek to violate its precinct. So on comprehending what they proposed, he sent to the two Rabbins to ask them about the affair. They replied: 'These folk intend naught but to destroy thee and thine army; we wot not of any house in the world that God hath chosen for Himself, save this. If thou do that to which they invite thee, thou and those with thee will surely perish together.' He said: 'What then is it ye bid me do when I come there?' They said: 'Thou wilt do as its people do—make the circuit thereof, and magnify and honour it, and shave thy head, and humble thyself before it, until thou go forth from its precinct.' He said: 'And what hinders you from doing that yourselves?' 'By God,' said they, 'it is the temple of our father Abraham, and verily it is even as we told thee, but we are debarred therefrom by the idols which its people have set up around it and by the blood-offerings which they make beside it; for they are vile polytheists,' or words to the same effect. The king perceived that their advice was good and their tale true. He ordered the Hudhalites to approach, and cut off their hands and feet. Then he continued his march to Mecca, where he made the circuit of the temple, sacrificed camels, and shaved his head. According to what is told, he stayed six days at Mecca, feasting the inhabitants with the flesh of camels and letting them drink honey.63... Then he moved out with his troops in the direction of Yemen, the two Rabbins accompanying him; and on entering Yemen he called on his subjects He seeks to establish Judaism in Yemen. to adopt the religion which he himself had embraced, but they refused unless the question were submitted to the ordeal of fire which at that time existed in Yemen; for as the Yemenites say, there was in their country a fire that gave judgment between them in their disputes: it devoured the wrong-doer but left the injured person unscathed. The Yemenites therefore came forward with their The ordeal of fire. idols and whatever else they used as a means of drawing nigh unto God, and the two Rabbins came forward with their scriptures hung on their necks like necklaces, and both parties seated themselves at the place from which the fire was wont to issue. And the fire blazed up, and the Yemenites shrank back from it as it approached them, and were afraid, but the bystanders urged them on and bade them take courage. So they held out until the fire enveloped them and consumed the idols and images and the men of Ḥimyar, the bearers thereof; but the Rabbins came forth safe and sound, their brows moist with sweat, and the scriptures were still hanging on their necks. Thereupon the Ḥimyarites consented to adopt the king's religion, and this was the cause of Judaism being established in Yemen."64

The poem addressed to his son and successor, Ḥassán, which tradition has put into his mouth, is a sort of last will and testament, of which the greater part is taken As‘ad's farewell to his son. up with an account of his conquests and with glorification of his family and himself.65 Nearly all that we find in the way of maxims or injunctions suitable to the solemn occasion is contained in the following verses:—

"O Ḥassán, the hour of thy father's death has arrived at last: Look to thyself ere yet the time for looking is past. Oft indeed are the mighty abased, and often likewise Are the base exalted: such is Man who is born and dies.

Bid ye Ḥimyar know that standing erect would I buried be, And have my wine-skins and Yemen robes in the tomb with me.66 And hearken thou to my Sibyl, for surely can she foresay The truth, and safe in her keeping is castle Ghaymán aye.67

In connection with Ghaymán a few words may be added respecting the castles in Yemen, of which the ruined skeletons rising from solitary heights seem still to frown The castles of Yemen. defiance upon the passing traveller. Two thousand years ago, and probably long before, they were occupied by powerful barons, more or less independent, who in later times, when the Ḥimyarite Empire had begun to decline, always elected, and occasionally deposed, their royal master. Of these castles the geographer Hamdání has given a detailed account in the eighth book of his great work on the history and antiquities of Yemen entitled the Iklíl, or 'Crown.'68 The oldest and most celebrated was Ghumdán, the citadel of Ṣan‘á. It is described as a huge edifice of twenty stories, each story ten cubits high. The Ghumdán. four façades were built with stone of different colours, white, black, green, and red. On the top story was a chamber which had windows of marble framed with ebony and planewood. Its roof was a slab of pellucid marble, so that when the lord of Ghumdán lay on his couch he saw the birds fly overhead, and could distinguish a raven from a kite. At each corner stood a brazen lion, and when the wind blew it entered the hollow interior of the effigies and made a sound like the roaring of lions.

The adventure of As‘ad Kámil with the three witches must have recalled to every reader certain scenes in Macbeth. Curiously enough, in the history of his son Ḥassán an incident is related which offers a striking parallel to the march of Birnam Wood. Ṭasm and Jadís have already been mentioned. On the massacre of the former tribe by the latter, a single Ṭasmite named Ribáḥ b. Murra made his escape and took refuge with the Tubba‘ Ḥassán, whom he persuaded to lead an expedition against the murderers. Now Ribáḥ's sister had married a man of Jadís. Her name was Zarqá’u ’l-Yamáma. Zarqá’u ’l-Yamáma— i.e., the Blue-eyed Woman of Yamáma—and she had such piercing sight that she was able to descry an army thirty miles away. Ḥassán therefore bade his horsemen hold in front of them leafy branches which they tore down from the trees. They advanced thus hidden, and towards evening, when they had come within a day's journey, Zarqá said to her people: "I see trees marching." No one believed her until it was too late. Next morning Ḥassán fell upon them and put the whole tribe to the sword.

The warlike expeditions to which Ḥassán devoted all his energy were felt as an intolerable burden by the chiefs of Ḥimyar, who formed a plot to slay him and set Ḥassán murdered by his brother. his brother ‘Amr on the throne. ‘Amr was at first unwilling to lend himself to their designs, but ultimately his scruples were overcome, and he stabbed the Tubba‘ with his own hand. The assassin suffered a terrible punishment. Sleep deserted him, and in his remorse he began to execute the conspirators one after another. There was, however, a single chief called Dhú Dhú Ru‘ayn. Ru‘ayn, who had remained loyal and had done his best to save ‘Amr from the guilt of fratricide. Finding his efforts fruitless, he requested ‘Amr to take charge of a sealed paper which he brought with him, and to keep it in a safe place until he should ask for it. ‘Amr consented and thought no more of the matter. Afterwards, imagining that Dhú Ru‘ayn had joined in the fatal plot, he gave orders for his execution. "How!" exclaimed Dhú Ru‘ayn, "did not I tell thee what the crime involved?" and he asked for the sealed writing, which was found to contain these verses—
