[Sidenote: Arthur in Avalon.] It was because Arthur thus disappeared and was never seen again, according to one version of the myth, and because none knew whether he were living or dead, that he was popularly supposed to be enjoying perpetual youth and bliss in the fabled island of Avalon, whence they averred he would return when his people needed him. This belief was so deeply rooted in England that Philip of Spain, upon marrying Mary, was compelled to take a solemn oath whereby he bound himself to relinquish the crown in favor of Arthur should he appear to claim it. "Still look the Britons for the day Of Arthur's coming o'er the sea." LAYAMON, _Brut_. Other romances and poems relate that Arthur was borne in the sable-hung barge to Glastonbury, where his remains were laid in the tomb, while Guinevere retired into the nunnery at Almesbury. There she was once more visited by the sorrowing Lancelot, who, in spite of all his haste, had come upon the scene too late to save or be reconciled to the king, to whom he was still devotedly attached. In his sorrow and remorse the knight withdrew into a hermitage, where he spent six years in constant penance and prayer. At last he was warned in a vision that Guinevere was no more. He hastened to Almesbury, and found her really dead. After burying her by Arthur's side, in the chapel of Glastonbury, Lancelot again withdrew to his cell. Six weeks later, worn to a shadow by abstinence and night watches, he peacefully passed away, and a priest watching near him said that he had seen the angels receive and bear his ransomed spirit straight up to heaven. Lancelot was buried either at Arthur's feet or at Joyeuse Garde. He was deeply mourned by all his friends, and especially by his heir, Sir Ector de Maris, who eulogized him in the following touching terms: "'Ah, Sir Lancelot,' he said, 'thou were head of all Christian knights; and now I dare say,' said Sir Ector, 'that, Sir Lancelot, there thou liest, thou were never matched of none earthly knight's hands; and thou were the courtliest knight that ever bare shield; and thou were the truest friend to thy lover that ever bestrode horse; and thou were the truest lover of a sinful man that ever loved woman; and thou were the kindest man that ever struck with sword; and thou were the goodliest person that ever came among press of knights; and thou were the meekest man, and the gentlest, that ever ate in hall among ladies; and thou were the sternest knight to thy mortal foe that ever put spear in rest.'"
