F a e r y * Q u e e n e

When I read the letter for the first time, it was really difficult to understand it. Then, for the second reading I was more prepared.
Having a better understanding about the letter I feel able to answer the questions.

Spenser wrote about King Arthur because he represents an extremely good man who possesses the most recognizable and important distinctiveness in those times. In addition, this story is related to an allegory because the author used symbolic figures for representing human characteristics that express the idea of brilliance. He also wanted to put emphasis on the attributes that were significant. For instance, Red Crosse represented holinesse; Sir Guyon intended temperance and Lady Knight expressed chastitie. All of them seen as symbolism of greatness.

I think that the purpose of writing this letter was for protecting himself from social problems, religious conflicts and evil temptation. He sent it to Sir Walter Raleigh because he was the best example of magnificence he was a well known man who could provide that protection and security.
