Iwein

Iwein is a Middle High German verse romance by the poet Hartmann von Aue, written around 1203. An Arthurian tale freely adapted from Chrétien de Troyes' Old French Yvain, the Knight of the Lion, it tells the story of Iwein (Ywain), a knight of King Arthur's Round Table. It was written after Hartmann's Erec, and may have been his last work.

Hartmann von Aue, because of his romance Erec, written around 1180, is considered the founder of German Arthurian Legend.

Iwein is his second courtly romance; on the basis of stylistic evidence, it is considered to be the last of Hartmann's total of four works. Between Erec and Iwein he created his two legendary stories Gregorius and Der arme Heinrich. Iwein must have been produced by 1205, as Wolfram von Eschenbach makes mention of it in his Parzival. The earliest possible creation date is usually taken to be the year 1190. Linguistic investigations seem to suggest that Iwein was begun shortly after Erec, but that Hartmann's work on it was interrupted after approximately 1000 verses. It is possible this is the result of the death of the patron. According to this theory, Hartmann only finished the poem at a later date. It is not known who commissioned Iwein, but the Zähringer, the Staufer and the Welfen have all been considered as possible patrons.
