According to Wace and Layamon, fighting erupted between the nobles over the seating arrangement. Every king and baron wanted to be seated at the head of the table or near King Arthur, so that they would be seen as having precedence over others.
To resolve these problems, Arthur has a large, rounded table constructed. Arthur also has every seated member of the Round Table, served at the same time. The ingenuity of this design, make all the knights equal, regardless if he was a king or a minor baron. Thus, no one would have precedence over others.
How this relates to our sweet Arthur? We all need to put our egos aside and treat all that care about Arthur as equals. In this way we can work togather for a victory.
