Had one fair daughter, and none other child,

            And she was fairest of all flesh on earth,

            Guenevere, and in her his one delight."

                                            Tennyson.

Guinevere, as everyone knows, was the wife of King Arthur. One of the earliect romances, Chrétien de Troyes' -  Lancelot, the Knight of the Cart, is the first to tell, what is probably the best known story of Guinevere, the adultery of Lancelot, Arthur's friend and the queens champion, and Guinevere. The affair which brings everything crashing down.

The Historia mentions the isle of Avalon, where Arthur went to recover from wounds after his last battle, and it tells of Guinevere's infidelity with Lancelot and the rebellion instigated by Arthur's nephew Mordred.
