(a) That some, or all, of the supernatural stories told of Beowulf the Geat, son of Ecgtheow (especially the Grendel-struggle and the dragon-struggle), were originally told of Beowulf the Dane, son of Scyld, who can be identified with the Beow or Beaw[[524]] of the genealogies.
(b) That this Beow was an ancient "god of agriculture and fertility."
(c) That therefore we can allegorize Grendel and the dragon into culture-myths connected with the "god Beow."
Now (c) would not necessarily follow, even granting (a) and (b); for though a hero of story be an ancient god, many of his most popular adventures may be later accretion. However, these two propositions (a) and (b) would, together, establish a very strong probability that the Grendel-story and the dragon-story were ancient culture-myths, and would entitle to a sympathetic hearing those who had such an interpretation of them to offer.
That Beow is an ancient "god of agriculture and fertility," I believe to be substantially true. We shall see that a great deal of evidence, unknown to Kemble and Müllenhoff, is now forthcoming to show that there was an ancient belief in a corn-spirit Beow: and this Beow, whom we find in the genealogies as son of Scyld or Sceldwa and descendant of Sceaf, is pretty obviously identical with Beowulf, son of Scyld Scefing, in the Prologue of Beowulf.
So far as the Prologue is concerned, there is, then, almost certainly a remote mythological background. But before we can claim that this background extends to the supernatural adventures attributed to Beowulf, son of Ecgtheow, we must prove our proposition (a): that these adventures were once told, not of Beowulf, son of Ecgtheow, but of Beowulf or Beow, son of Scyld.
When it was first suggested, at the very beginning of Beowulf-criticism, that Beowulf was identical with the Beow of the genealogies, it had not been realized that there were in the poem two persons named Beowulf: and thus an anonymous scholar in the Monthly Review of 1816[[525]], not knowing that Beowulf the slayer of Grendel is (at any rate in the poem as it stands) distinct from Beowulf, son of Scyld, connected both with Beow, son of Scyld, so initiating a theory which, for almost a century, was accepted as ascertained fact.
Kemble's identification was probably made independently of the work of this early scholar. Unlike him, Kemble, of course, realized that in our poem Beowulf the Dane, son of Scyld, is a person distinct from, is in fact not related to, Beowulf son of Ecgtheow. But he deliberately identified the two: he thought that two distinct traditions concerning the same hero had been amalgamated: in one of these traditions Beowulf may have been represented as son of Scyld, in the other as son of Ecgtheow, precisely as the hero Gunnar or Gunter is in one tradition son of Gifica (Giuki), in another son of Dankrat.
