Upon the ancient legend which has thus been outlined Wagner reared his great tragedy entitled "Tristan und Isolde." Whence the story came nobody can tell. It is a part of the great treasure preserved from remotest antiquity by itinerant singers and story-tellers, and committed to writing by poets of the Middle Ages. The first of these, so far as unquestioned evidence goes, were French trouvères. From them the tale passed into the hands of the German minnesinger. The greatest of these who treated it was Gottfried von Strasburg (circa A.D. 1210), who, however, left the tale unfinished. His continuators were Ulrich von Türnheim and Heinrich von Freiberg, whose denouement (not, however, original with them) was followed by Hermann Kurtz when he published a version of Gottfried's poem in modern German in 1844. This, unquestionably, was the version which fell into Wagner's hands when, in the Dresden period (1843-1849) he devoted himself assiduously to the study of Teutonic legend and mythology. In English the romance has an equally honorable literary record. In 1804 Sir Walter Scott edited a metrical version which he fondly believed to be the work of the somewhat mythical Thomas the Rhymer and to afford evidence that the oldest literary form of the legend was British. The adventures of Tristram of Lyonesse (who is the Tristan of Wagner's tragedy) form a large portion of Sir Thomas Malory's thrice glorious "Morte d'Arthur." Of modern poets Tennyson, Matthew Arnold, and Swinburne have sung the passion of the ill-starred lovers. Elements of the legend can be traced back to the ancient literatures of the Aryan peoples. The courtship by proxy has a prototype in Norse mythology in Skirnir's wooing of Gerd for Van Frey. The incident of the sails belongs to Greek story--the legend of AEgeus and Theseus; the magic potion may be found in ancient Persian romance; the interlocked rose-tree and vine over the grave of the lovers is an example of those floral auguries and testimonies which I have mentioned in connection with the legend of Tannhäuser and the blossoming staff: in token of their innocence flowers spring miraculously from the graves of persons wrongly done to death.
