A constitution is a statement of the basic principles and laws of a nation, state, or group, such as the U.S. Constitution. Another very common meaning of constitution is the physical makeup of a person. So think of a constitution as how a body (yours, the government's) is set up. If you have a strong constitution, it means you don't get sick very often.
I think the focus of the story is on Beowulf as a hero rather than a king because it is his heroic deeds that lead to him being offered the throne. Also to be king one must possess some type of heroic qualities in order to rule a land and its people.
Trait 3: Great Warrior ï¶ Before the hero of an epic does his business in the epic, he has usually established himself in combat during a war. ï¶ Sometimes, as in The Iliad, we see the hero at war. ï¶ In most, like Beowulfand The Odyssey, the hero has spent much time in battle. Trait 4: Travels Over a Vast Setting ï¶ Simply put, you cannot be an epic hero if you stay in your village your whole life. ï¶ The more countries or areas traveled to, the better. The farther away from your own country, the better.
