Beowulf, a very old Anglo-Saxon romance consisting of 6356 short alliterative lines, and the oldest extant in the language, recording the exploits of a mythical hero of the name, who wrestled Hercules-wise, at the cost of his life, with first a formidable monster, and then a dragon that had to be exterminated or tamed into submission before the race he belonged to could live with safety on the soil.
