There are people, no doubt, for whom Peer Gynt and the trolls, Uistean Mor and the warlock, even Selkolla that Bishop Gudmund killed, are as impossible as the dragon in the end of the poem of _Beowulf_. But it is certain that stories like those of Grendel are commonly believed in many places where dragons are extinct. The story of Beowulf and Grendel is not wildly fantastic or improbable; it agrees with the conditions of real life, as they have been commonly understood at all times except those of peculiar enlightenment and rationalism. It is not to be compared with the Phaeacian stories of the adventures of Odysseus. Those stories in the _Odyssey_ are plainly and intentionally in a different order of imagination from the story of the killing of the suitors. They are pure romance, and if any hearer of the _Odyssey_ in ancient times was led to go in search of the island of Calypso, he might come back with the same confession as the seeker for the wonders of Broceliande,--_fol i alai_. But there are other wonderful things in the _Iliad_ and the _Odyssey_ which are equally improbable to the modern rationalist and sceptic; yet by no means of the same kind of wonder as Calypso or the Sirens. Probably few of the earliest hearers of the _Odyssey_ thought of the Sirens or of Calypso as anywhere near them, while many of them must have had their grandmothers' testimony for things like the portents before the death of the suitors. Grendel in the poem of _Beowulf_ is in the same order of existence as these portents. If they are superstitions, they are among the most persistent; and they are superstitions, rather than creatures of romance. The fight with Grendel is not of the same kind of adventure as Sigurd at the hedge of flame, or Svipdag at the enchanted castle. And the episode of Grendel's mother is further from matter of fact than the story of Grendel himself. The description of the desolate water is justly recognised as one of the masterpieces of the old English poetry; it deserves all that has been said of it as a passage of romance in the middle of epic. Beowulf's descent under the water, his fight with the warlock's mother, the darkness of that "sea dingle," the light of the mysterious sword, all this, if less admirably worked out than the first description of the dolorous mere, is quite as far from Heorot and the report of the table-talk of Hrothgar, Beowulf, and Hunferth. It is also a different sort of thing from the fight with Grendel. There is more of supernatural incident, more romantic ornament, less of that concentration in the struggle which makes the fight with Grendel almost as good in its way as its Icelandic counterpart, the wrestling of Grettir and Glam.
