The border between fact and fiction becomes blurred in legend, stories which themselves have a history, and in their evolving shape they carry the imprint of all the hands that passed them. Through the Internet, students can track the growth of a legend like that of King Arthur, from its emergence in the so-called Dark Ages to its arrival on the silver screen. The learning objectives of this lesson plan are: to examine the historical origins of the Arthurian legend; to investigate how medieval historians and storytellers reflected the concerns of their own times in their treatment of the legend; and to gain insight into the use of literature as historical evidence. The lesson plan also contains the subject areas covered in the lesson, time required to complete the lesson, the skills used in the lesson, the grade level (9-12), and lists of the standards developed by professional or government associations that are related to the lesson, as well as activities to extend the lesson.
