Tristan and Iseult

The Story in Outline

Tristan is the orphaned nephew of King Mark of Cornwall, raised at his uncle's court and quickly the best of his knights. When the Irish champion Morholt comes to demand tribute, Tristan kills him, but takes a poisoned wound that no Cornish physician can close; drifting to Ireland in an open boat under the assumed name Tantris, he is healed by the dead champion's niece, the princess Iseult, who does not yet know whose sword left the splinter in her uncle's skull ^1,2,3. Later Mark sends him back to win that same princess as a bride. On the voyage home the two of them drink, by mistake, a love philtre that Iseult's mother had brewed for the wedding night ^1,2.

Everything after that is consequence. Iseult marries Mark, and her maid Brangain takes her place in the dark of the bridal chamber; the lovers meet in the orchard, are spied on, are trapped, escape, are condemned, are pardoned; they live rough in the forest of Morrois until Mark finds them asleep with a drawn sword between them and leaves his glove against the sunlight instead of killing them ^1,3. Iseult clears herself by an oath crafted so as to be literally true and wholly deceptive. Tristan goes into exile in Brittany and marries a second Iseult, Iseult of the White Hands, whom he never touches ^2,3.

The end is the most famous scene in medieval romance. Wounded past healing, Tristan sends for Iseult of Ireland, arranging that the returning ship fly a white sail if she is aboard and a black one if she is not. His jealous wife tells him the sail is black. He dies; Iseult lands, finds him dead, and dies beside him; and from their graves grow a bramble and a vine, or two trees, that twine together and cannot be cut apart ^2,3,6.

Beroul, Thomas, and the Two Traditions

No complete early version survives. What we have are fragments, and scholars have long sorted them into two branches. The so-called version commune, represented by Beroul's Anglo-Norman poem and by Eilhart von Oberge's German Tristrant, is rougher, more violent and closer to folk narrative; the version courtoise, represented by Thomas of Britain and by Gottfried, is introspective, analytical and interested in what the lovers feel ^1,2,6,8.

The difference shows most sharply in the potion. In Beroul its power lasts three years, after which the lovers come to themselves in the forest and begin to regret the life they have been living — which makes the story a tale of enchantment and its wearing off ¹. In Thomas the potion is permanent, less a spell than a symbol of a love that was always going to happen, and the moral question of guilt becomes correspondingly harder ^2,6. Both readings survive in later retellings, and the tension between them is arguably why the legend never settled into a single moral ^6,8.

Gottfried's Tristan

Gottfried von Strassburg's Tristan, written around 1210 and left unfinished, is generally regarded as the artistic summit of the material ^3,6. He follows Thomas but pushes further, treating the lovers' passion as something close to a religion with its own martyrs; the celebrated episode of the Cave of Lovers turns their forest exile into an allegorical chapel, its dimensions and furnishings glossed one by one. Gottfried is also openly hostile to the moralists in his audience, addressing his poem to edele herzen, noble hearts capable of understanding a love that costs everything ^3,6.

Absorbed into the Round Table

Tristan was not originally an Arthurian character. The vast thirteenth-century Prose Tristan pulled him into the orbit of King Arthur's court, made him a knight of the Round Table, gave him a rivalry and then a friendship with Lancelot, and set his adultery with Iseult in deliberate parallel to Lancelot's with Guinevere ^5,8. In this tradition Mark degenerates from a wronged and often sympathetic king into a treacherous villain who murders his nephew at the harp, and Morgan le Fay appears as one of Tristan's tormentors ⁵. Malory took his Books VIII-XII from the Prose Tristan, which is why Sir Tristram occupies roughly a third of Le Morte d'Arthur ^5,8.

Celtic Roots and Long Shadows

Older strata are visible behind the French. The Welsh Triads know Drystan son of Tallwch, Essyllt, and March son of Meirchion, and treat Drystan as one of the great swineherds and lovers of Britain, which suggests the trio circulated in Wales and Cornwall independently of the romances ⁷. A sixth-century inscribed stone near Fowey in Cornwall, the Tristan Stone, records a Drustanus son of Cunomorus; the identification with the legend is old, popular, and not accepted as established by most archaeologists ^7,8. Scholars have also compared the Irish tales of Diarmuid and Grainne and of Deirdre and Naoise, where a young man elopes with the intended bride of an older king, though whether these are sources, cousins or coincidences remains debated ^6,7.

Marie de France's short lai "Chevrefoil" gives the legend its gentlest image: Tristan carves his name on a hazel branch to signal a meeting, and the honeysuckle and hazel twined together stand for two people who die if separated ⁴. Seven centuries later Wagner's Tristan und Isolde (first performed 1865) rebuilt the story around Gottfried and, in doing so, changed the direction of European music. The names that reach most modern audiences — Isolde, Brangane, Kurwenal — come from that German line rather than the French ^3,6,8.
