King Arthur:

Although King Arthur's appearance in the epic Sir Gawain and the Green Knight is brief, a reader may notice his childish behavior in the beginning of the poem. In the midst of the Christmas party, Arthur refuses to eat unless he hears an entertaining story:

		But Arthur would not eat till all were served;
		So light was his lordly heart, and a little boyish;
		... he nobly had willed, he would never eat
		On so high a holiday, till he had heard first
		Of some fair feat or fray some far-borne tale... (ll 85-93).

Such behavior is incompatible with other literary sources, such as Morte Darthur by Sir Thomas Malory, where Arthur is described as a powerful, just and courageous king.
