Poets in those days found favour with princes. A great number of Pre-islamic bards visited the Lakhmite court, while some, like Nábigha and ‘Abíd b. al-Abraṣ, made it their permanent residence. [Sidenote: The Lakhmites.] [Sidenote: Nu‘mán I. (_circa_ 400 A.D.).] [Sidenote: The Castle of Khawarnaq.] [Sidenote: Nu‘mán becomes an anchorite.] It is unnecessary to enter into the vexed question as to the origin and rise of the Lakhmite dynasty at Ḥíra. According to Hishám b. Muḥammad al-Kalbi, who gives a list of twenty kings, covering a period of 522 years and eight months, the first Lakhmite ruler was ‘Amr b. ‘Adí b. Naṣr b. Rabí‘a b. Lakhm, the same who was adopted by Jadhíma, and afterwards avenged his death on Queen Zabbá. Almost nothing is known of his successors until we come to Nu‘mán I, surnamed al-A‘war (the One-eyed), whose reign falls in the first quarter of the fifth century. Nu‘mán is renowned in legend as the builder of Khawarnaq, a famous castle near Ḥíra. It was built at the instance of the Sásánian king, Yazdigird I, who desired a salubrious residence for his son, Prince Bahrám Gór. On its completion, Nu‘mán ordered the architect, a 'Roman' (_i.e._, Byzantine subject) named Sinimmár, to be cast headlong from the battlements, either on account of his boast that he could have constructed a yet more wonderful edifice "which should turn round with the sun," or for fear that he might reveal the position of a certain stone, the removal of which would cause the whole building to collapse. One spring day (so the story is told) Nu‘mán sat with his Vizier in Khawarnaq, which overlooked the Fen-land (al-Najaf), with its neighbouring gardens and plantations of palm-trees and canals, to the west, and the Euphrates to the east. Charmed by the beauty of the prospect, he exclaimed, "Hast thou ever seen the like of this?" "No," replied the Vizier, "if it would but last." "And what is lasting?" asked Nu‘mán. "That which is with God in heaven." "How can one attain to it?" "By renouncing the world and serving God, and striving after that which He hath." Nu‘mán, it is said, immediately resolved to abandon his kingdom; on the same night he clad himself in sackcloth, stole away unperceived, and became a wandering devotee (_sá’iḥ_). This legend seems to have grown out of the following verses by ‘Adí b. Zayd, the ‘Ibádite:-- "Consider thou Khawarnaq's lord--and oft Of heavenly guidance cometh vision clear-- Who once, rejoicing in his ample realm, Surveyed the broad Euphrates, and Sadír;[85] Then sudden terror struck his heart: he cried, 'Shall Man, who deathward goes, find pleasure here?' They reigned, they prospered; yet, their glory past, In yonder tombs they lie this many a year. At last they were like unto withered leaves Whirled by the winds away in wild career."[86]
