Thomas of Britain

Who is Thomas of Britain?

Thomas of Britain was a poet of the 12th century. He is known for his Old French poem Tristan, a version of the Tristan and Iseult legend that exists only in eight fragments, amounting to around 3,300 lines of verse, mostly from the latter part of the story. It is calculated that this represents about one sixth of the original.

Because Thomas has an "obvious dependence" on Wace's 1155 Roman de Brut, Tristan was written between 1155 and 1160, possibly for Eleanor of Aquitaine, since the work suggests close ties with the court of Henry II. Beyond this, his identity is obscure; it has been speculated that he is to be identified with the "Thomas" who wrote the Romance of Horn, but this is unsupported. It is similar to the Tristan-story Chevrefoil by Marie de France, but either author could have borrowed from the other, or both from a third source.

Although Thomas's own text is fragmentary, later adaptations of his work make it possible to reconstruct what is missing:

Gottfried von Strassburg's Tristan, left incomplete c. 1210, though fortuitously it covers all those parts of Thomas's work which are lost. Gottfried expanded the story by about a third, while nonetheless remaining fairly faithful to Thomas.
