Write an analysis of Sir Ector de Maris’s elegy for his brother Lancelot (553, beginning at “Ah, Lancelot!” at ending at “put spear in the rest”).

Write an analysis of Sir Ector de Maris’s elegy for his brother Lancelot (553, beginning at “Ah, Lancelot!” at ending at “put spear in the rest”). Do not write out the whole passage and then make a paraphrase of it, for I will have the passage in front of me when I grade your work. Nor should you write the passage out bit by bit with accompanying paraphrase, for again I can see all of the words myself.
The best approach will be to re-read the passage several times, taking notes. Then see if you can create a list or diagram of Lancelot’s leading traits. As you do so, determine to what extent some sort of structure underlies Ector’s elegy. If you create a structured document of your own, you will be in a position to compare your organizational strategy with his. How many paragraphs would you need to clarify the nature of Lancelot’s various traits and how they relate to each other?
When you do quote from the elegy, you will do so as evidence supporting the accuracy of your interpretation of what Lancelot ultimately was. In other words, your task is to perceive why someone might admire him so highly, while preserving the detachment that will allow you to engage in critical thinking. As a brother, Ector is not surprisingly partial in his view of Lancelot. All the indications are that Malory shared that partiality and expected his readers to do so too. But his readers (now) are not persons living in the Middle Ages, that is, they are in this context you. Your mission is not to do a hatchet job on Lancelot, for this would only reveal your inability to respond sympathetically to Ector’s and Malory’s values. But you do not have the same understanding of virtue, heroism, or other pertinent traits, so you can learn about your own values and about those values typical of the Middle Ages by putting Ector’s words into the context of your own words. passage below……
“Ah, Lancelot!” he said, “thou were head of all Christian knights. And now i dare say,” said Sir Ector, “thou Sir Lancelot, there thou liest, that thou were never matched of earthly knights’s hand. And thou were the courteoust(most courteous) knight that ever bore shield. And thou were the truest friend to thy lover that ever bestrode horse, and thou were the truest lover, of a sinful man,(of any man born in original sin) that ever loved women, and thou were the kindest man that ever struck with sword. And thou were the goodliest person that ever came among press of knights, and thou was the meekest man and the gentlest that ever ate in hall among ladies, and thou were the sternest knight to thy mortal foe that ever put spear in the rest.”(support for the butt of the lance)
