Thus made aware of their danger, the lovers again decided to part, and Tristan, deprived for a time of the sight of Iseult, went mad, and performed many extraordinary feats; for mediaeval poets generally drove their heroes into a frenzy when they did not know what else to do with them. Having recovered, and hoping to forget the fatal passion which had already caused him so much sorrow, Tristan now wandered off to Arthur's court, where he performed many deeds of valor. Thence he went on to various strange lands, distinguishing himself greatly everywhere, until he received from a poisoned arrow a wound which no doctor could heal.
[Sidenote: Iseult of Brittany.] Afraid to expose himself again to the fascinations of Iseult of Cornwall, Tristan went to Brittany, where another Iseult,—with the White Hands,—equally well skilled in medicine, tenderly nursed him back to health. This maiden, as good and gentle as she was beautiful, soon fell in love with the handsome knight, and hearing him sing a passionate lay in honor of Iseult, she fancied that her affections were returned, and that it was intended for her ear.
"I know her by her mildness rare,
Her snow-white hands, her golden hair;
I know her by her rich silk dress,
And her fragile loveliness,—
The sweetest Christian soul alive,
Iseult of Brittany."
MATTHEW ARNOLD, Tristram and Iseult.
The brother of this fair Iseult saw her love for Tristan, and offered him her hand, which he accepted more out of gratitude than love, and in the hope that he might at last overcome the effects of the fatal draught. But, in spite of all his good resolutions, he could not forget Iseult of Cornwall, and treated his wife with such polite coolness that her brother's suspicions were finally roused.
Tristan, having conquered a neighboring giant and magician by the name of Beliagog, had granted him his life only upon condition that he would build a marvelous palace in the forest, and adorn it with paintings and sculptures, true to life, and representing all the different stages of his passion for Iseult of Cornwall. When his brother-in-law, therefore, asked why he seemed to find no pleasure in the society of his young wife, Tristan led him to the palace, showed him the works of art, and told him all. Ganhardin, the brother-in-law, must evidently have considered the excuse a good one, for he not only forgave Tristan, but implored him to take him to Cornwall, for he had fallen in love with the picture of Brangwaine, and hoped to win her for wife. On the way thither the young knights met with sundry adventures, delivered Arthur from the power of the Lady of the Lake, and carried off Iseult, whom the cowardly Mark was ill treating, to Lancelot's castle of Joyeuse Garde. There she became acquainted with Guinevere, and remained with her until Arthur brought about a general reconciliation.
Then Tristan once more returned to Brittany, resumed his wonted knightly existence, and fought until he was wounded so sorely that Iseult of Brittany could not cure him. His faithful steward Kurvenal, hoping yet to save him, sailed for Cornwall to bring the other Iseult to the rescue; and as he left he promised his master to change the black sails of the vessel for white in case his quest were successful.
Tristan now watched impatiently for the returning sail, but just as it came into view he breathed his last. Some ill-advised writers have ventured to state that Iseult of Brittany, whose jealousy had been aroused, was guilty of Tristan's death by falsely averring, in answer to his feverish inquiry, that the long-expected vessel was wafted along by black sails; but, according to other authorities, she remained gentle and lovable to the end.
[Sidenote: Miracle of the plants.] Iseult of Cornwall, speeding to the rescue of her lover, whom nothing could make her forget, and finding him dead, breathed her last upon his corpse. Both bodies were then carried to Cornwall, where they were interred in separate graves by order of King Mark. But from the tomb of the dead minstrel there soon sprang a creeper, which, finding its way along the walls, descended into Iseult's grave. Thrice cut down by Mark's orders, the plant persisted in growing, thus emphasizing by a miracle the passionate love which made this couple proverbial in the middle ages. There are in subsequent literature many parallels of the miracle of the plant which sprang from Tristan's tomb, as is seen by the Ballad of Lord Thomas and Fair Annet, and of Lord Lovel, where, as in later versions of the Tristan legend, a rose and a vine grew out of the respective graves and twined tenderly around each other.
"And out of her breast there grew a red rose,
And out of his breast a brier."
Ballad of Lord Lovel.
