Beot
A bēot is Old English for a ritualized boast, vow, threat, or promise. The principle of a bēot is to proclaim one's acceptance of a seemingly impossible challenge in order to gain tremendous glory for actually accomplishing it.
Anglo-Saxon warriors would usually deliver bēots in the mead hall the night before a military engagement or during the battle itself. For example, a typical warrior may boast that he will be the first to strike a blow in a battle, that he would claim a renowned sword from enemy warrior as spoils of battle, that he will slay a particular monster that has been wreaking havoc on a town or village, and so on. Bēots were usually accompanied by grand stories of one's past glorious deeds. Although other cultures and times might disdain boasting as a sign of arrogance, or sinful pride, the pagan Anglo-Saxons highly regarded such behavior as a positive sign of one's determination, bravery, and character.
