Тристан и Изольда
Mark sends Tristan as his proxy to fetch his young bride, the Princess Iseult, from Ireland. Tristan and Iseult fall in love, and, with the help of a magic potion, proceed to have one of the stormiest love affairs in medieval literature. Mark suspects the affair and eventually his suspicions are confirmed. In some versions, he sends for Tristan to be hanged, and banishes Iseult to a leper colony. Tristan escapes the hanging and rescues Iseult from her confinement. Mark later discovers this and eventually forgives them, with Iseult returning to Mark and Tristan leaving the country. The story is cyclical with Mark suspecting Tristan and Iseult of adultery and then believing they were innocent. This happens again and again in the story. In Béroul's version, Tristan and Iseult are never in grave danger due to the narrator's declaration that he himself and God were on their side. Mark, in the role of husband, is not portrayed as idealistic as other kings in Arthurian literature who were only portrayed in the role of king and not the personal role of husband.
