He too, when restored to his senses, visits Arthur's court, is admitted to the Round Table, and joins in the Quest for the Holy Grail, which, of course, he cannot achieve. Then he does marvels in the matter of hunting and fighting, and, having received another dangerous wound, wonders who besides Iseult of Cornwall can cure it? It is then he hears for the first time of Iseult of Brittany (or of the White Hands), whose skill in such matters is proverbial, and, seeking her aid, is soon made whole. But meantime the physician has fallen in love with her patient, and fancies her love is returned because every lay he sings is in praise of Iseult! Her brother, discovering her innocent passion, reveals it to Tristram, who, through gratitude or to drive the remembrance of his guilty passion out of his mind, finally marries her. But even marriage cannot make him forget Iseult of Cornwall. The time comes when, wounded beyond the power of his wife's skill to cure, Tristram sends for Iseult of Cornwall, who, either owing to treachery or to accident, arrives too late, and dies of grief on her lover's corpse. Some legends vary greatly in the manner of Tristram's death, for he is sometimes slain by King Stark, who is justly angry to find him in his wife's company. Most of the versions, however, declare that the lovers were buried side by side, and that creepers growing out of their respective graves twined lovingly around each other. Other beautiful episodes which are taken from old Welsh versions of the Arthurian legends are the stories of Geraint and Enid, of Pelleas and Ettarre, of Gareth and Lynette, which have received their latest and most beautiful setting at the hands of the poet-laureate Tennyson, and the very tragic and pathetic tale of the twin brothers Balin and Balan, who, after baleful happenings galore, failing to recognize each other, fight until one deals the "dolorous stroke" which kills his brother. Were any one patient enough to count the characters, duels, and hair-breadth escapes in Malory's Morte d'Arthur, the sum might well appall a modern reader. Magic, too, plays a prominent part in the Arthurian cycle, where Merlin, by means of a magic ring given by the Lady of the Lake to her sister Vivien, becomes so infatuated with the latter lady, that she is able to coax from him all his secrets, and even to learn the spell whereby a mortal can be kept alive although hidden from all eyes. Having obtained the magic formula by bringing all her coquettish wiles to bear upon besotted old Merlin, Vivien is said to have decoyed the wizard either to an enchanted castle, where she enclosed him in a stone sepulchre, or into the forest of Broceliande, in Brittany, where she left him, spellbound in a flowering thorn-bush. Another legend, however, claims that, having grown old and forgetful, Merlin absent-mindedly attempted to sit down in the Siege Perilous, only to be swallowed up by the yawning chasm which opened beneath his feet.
