Thomas of Britain

Thomas of Britain (also known as Thomas of England) 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.
Works.
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:
Thomas' version is the earliest known representative of the "courtly branch" of the legend, to which Gottfried's also belongs. This branch differs from the "common" or "primitive" versions of Béroul and Eilhart von Oberge, in that greater emphasis is placed on pleasing the sensibilities and expectations of a courtly audience. Some scholars have theorized an "Ur-Tristan", an original French version that inspired all later accounts. Joseph Bédier attempted to reconstruct this original from the evidence provided by the later versions.
