" This work quotes and attacks W. P. Ker's assertion that "there are other things in the lives of Hercules and Thesues besides the killing of the Hydra or of Procrustes," whereas another figure has "nothing else to do. " Claiming that "a man might well exchange for one good dragon what he would not sell for a wilderness," this essay notes that there are only two important dragons in all of northern literature, the other being Fafnir.
