In The Once and Future King by TH White what four phases has the court of Camelot gone through?

In T.H. White's 'The Once and Future King,' there are four separate phases of Camelot that correspond to part of the book. The first part is 'The SWord In The Stone,' and corresponds to Arthur first assuming the throne at Camelot. 'The Queen of Air and Darkness' corresponds to Arthur's development of the Round Table, and method of rule. 'The Ill-Made Knight' introduces Lancelot, his affair with the queen, and the breaking of the Round Table. The final part, 'The Candle In The Wind,' corresponds to Arthur's final days of life. Camelot is near an end, Guinevere and Lancelot are no longer in his life, and he is days before the final meeting with his illegitimate son, Mordred in battle. His concepts of ethics and morality are explored.
