We had ridden to the south-east for about three hours, through a most uncompromising wilderness, when, in the glare ahead, we caught sight of a great mass which I took for a natural feature in the landscape. But as we approached, its shape became more and more definite, and I asked one of the zaptiehs what it was.

“It is Kheiḍir,” said he.

“Yallah, Fattûḥ, bring on the mules,” I shouted, and galloped forward.

Of all the wonderful experiences that have fallen my way, the first sight of Kheiḍir is the most memorable. It reared its mighty walls out of the sand, almost untouched by time, breaking the long lines of the waste with its huge towers, steadfast and massive, as though it were, as I had at first thought it, the work of nature, not of man. We approached it from the north, on which side a long low building runs out towards the sandy depression of the Wâdî Lebai’ah ([Fig. 77]). A zaptieth caught me up as I reached the first of the vaulted rooms, and out of the northern gateway a man in long robes of white and black came trailing down towards us through the hot silence.

“Peace be upon you,” said he.

“And upon you peace, Sheikh ’Alî,” returned the zaptieh. “This lady is of the English.”

“Welcome, my lady Khân,” said the sheikh; “be pleased to enter and to rest.”

He led me through a short passage and under a tiny dome. I was aware of immense corridors opening on either hand, but we passed on into a great vaulted hall where the Arabs sat round the ashes of a fire.

“My lady Khân,” said Sheikh ’Alî, “this is the castle of Nu’mân ibn Mundhir.”

Whether it were a Lakhmid palace or no, it was the palace which I had set forth to seek. It belongs architecturally to the group of Sassanian buildings which are already known to us, and historically it is related to the palaces, famous in pre-Mohammadan tradition, whose splendours had filled with amazement the invading hordes of the Bedouin, and still shine with a legendary magnificence, from the pages of the chroniclers of the conquest. Even for the Mohammadan writers they had become nothing but a name. Khawarnaḳ, Sadîr, and the rest, fell into ruin with Ḥîrah, the capital of the small Arab principality that occupied the frontiers of the desert, and their site was a matter of hearsay or conjecture. “Think on the lord of Khawarnaḳ,” sang ’Adî ibn Zaid prophetically—
