Among these shorter epic poems, if such they may be called, there are to be distinguished great varieties of procedure in regard to the amount of action represented in the poem.
There is one class of poem that represents a single action with some detail; there is another that represents a long and complex story in a summary and allusive way. The first kind may be called episodic in the sense that it takes up about the same quantity of story as might make an act in a play; or perhaps, with a little straining of the term, as much as might serve for one play in a trilogy.
The second kind is not episodic; it does not seem fitted for a place in a larger composition. It is a kind of short and summary epic, taking as large a province of history as the Iliad or the Odyssey.
Hildebrand, the Fight at Finnesburh, Waldere, Byrhtnoth, the Winning of the Hammer, Thor's Fishing, the Death of the Niblungs (in any of the Northern versions), the Death of Ermanaric, might all be fairly regarded as belonging to the first kind of story; while the Lay of Weland and the Lay of Brynhild cover a much larger extent of story, though not of actual space, than any of those.
It is not quite easy to find a common measure for these and for the Homeric poems. One can tell perhaps from Mr. Arnold's poem of Sohrab and Rustum how much is wanting to the Lay of Hildebrand, and on what scale the story of Hildebrand might have been told if it had been told in the Homeric instead of the archaic German manner. The story of Walter of Aquitaine in the Latin hexameters of Waltharius takes up 1456 lines. Although the author of this Latin poem is something short of Homer, "a little overparted" by the comparison, still his work is designed on the scale of classical epic, and gives approximately the right extent of the story in classical form. But while those stories are comparatively short, even in their most expanded forms, the story of Weland and the story of Helgi each contains as much as would suffice for the plot of an Odyssey, or more. The Lay of Brynhild is not an episodic poem of the vengeance and the passion of Brynhild, though that is the principal theme. It begins in a summary manner with Sigurd's coming to the house of the Niblungs, the wedding of Sigurd and Gudrun, the wooing of Brynhild for Gunnar; all these earlier matters are taken up and touched on before the story comes to the searchings of heart when the kings are persuaded to kill Sigurd. Then the death of Sigurd is told of, and the rest of the poem is filled with the tragedy of Brynhild and Gudrun; the future history of Gudrun is spoken of prophetically by Brynhild before she throws herself on the funeral pile. Plainly this cannot be considered in the same sense "episodic" as the poem of Thor's fishing for the Midgarth snake. The poems of Thor's fishing and the recovery of the hammer are distinctly fragments of a legendary cycle. The Lay of Brynhild makes an attempt to complete the whole Volsung story from beginning to end, while giving special importance to one particular incident of it,—the passion of Brynhild after the death of Sigurd. The poems of Attila and the Lay of the Death of Ermanaric are more restricted.
It remains true that the great story of the Niblung tragedy was never told at length in the poetical measure used for episodes of it, and for the summary form of the Lay of Brynhild. It should be remembered, however, that a poem of the scale of the Nibelungenlied, taking up the whole matter, must go as far beyond the Homeric limit as the Lay of Brynhild falls short of it. From one point of view the shorter episodic poems are more Homeric in their plots than either the summary epics which cover the whole ground, as the Lay of Brynhild attempts to cover it, or the longer works in prose that begin at the beginning and go on to the end, like the Volsunga Saga. The Iliad and the Odyssey are themselves episodic poems; neither of them has the reach of the Nibelungenlied. It should not be forgotten, either, that Aristotle found the Iliad and the Odyssey rather long. The Teutonic poems are not to be despised because they have a narrower orbit than the Iliad. Those among them that contain matter enough for a single tragedy, and there are few that have not as much as this in them, may be considered not to fall far short of the standard fixed by Aristotle for the right amount of action to be contained in an heroic poem. They are too hurried, they are wanting in the classical breadth and ease of narrative; but at any rate they are comprehensible, they observe an epic unity. They do not, like certain of the endless French poetical histories, remind one of the picture of incomprehensible bulk in Aristotle's Poetics, the animal 10,000 stadia long.
Thus, though it is natural at first to imagine that in the old Teutonic poetry one is possessed of such separate lays or ballads as might be the original materials of a larger epic, an epic of the Homeric scale, this impression will hardly remain long after a closer criticism of the workmanship of the poems. Very few of them correspond in the amount of their story to the episodes of the Homeric poems. Many of them contain in a short space the matter of stories more complicated, more tragical, than the story of Achilles. Most of them by their unity and self-consistency make it difficult to think of them as absorbed in a longer epic. This is the case not only with those that take in a whole history, like the Lay of Brynhild, but also with those whose plot is comparatively simple, like Hildebrand or Waldere. It is possible to think of the story of Walter and Hildegund as forming part of a larger story of the fortunes of the Huns. It has this subordinate place in the Thidreks Saga. But it is not easy to believe that in such a case it preserves its value. Thidreks Saga is not an epic, though it is made by an agglutination of ballads. In like manner the tragedy of Hildebrand gains by its isolation from the stories of the other chiefs, Theodoric and Odoacer. The stories of Walter and of Hildebrand, like the story of Hamlet the Dane, are too strong in themselves to form part of a larger composition, without detriment to its unity and harmony. They might be brought in allusively and in a subordinate way, like the story of Thebes and other stories in the Iliad; but that is not the same thing as making an epic poem out of separate lays. So that on all grounds the first impression of the Teutonic epic poetry has to be modified. If ever epic poetry was made by a conglomeration of ballads, it must have had other kinds of material than this. Some of the poems are episodic; others are rather to be described as abridgments of epic than as separate epic scenes. But neither in the one case nor in the other is there to be found the kind of poetry that is required by the hypothesis of composite epic. There are short epics that might conceivably have served as the framework, or the ground-plan, of a more elaborate work, containing, like the Lay of Helgi or the Lay of Brynhild, incidents enough and hints of character enough for a history fully worked out, as large as the Homeric poems. If it should be asked why there is so little evidence of any Teutonic attempt to weave together separate lays into an epic work, the answer might be, first, that the separate lays we know are too much separate and individual, too strong in themselves, to be satisfactorily cobbled into a more expansive fabric; and, secondly, that it has not yet been proved that epic poems can be made by process of cobbling. The need of a comprehensive epic of the Niblungs was not imperative. Neither was there any demand in Athens, in the time of Sophocles and Euripides, for a comprehensive work—a Thebaid, a Roman de Thèbes—to include the plots of all the tragedies of the house of Cadmus. It was not a poet, but a prose journeyman, who did this sort of work in the North, and it was not till the old school of poetry had passed away that the composite prose history of the Volsungs and Niblungs, of Sigmund and Sinfiotli, Sigurd, Brynhild, Gudrun, and Atli, was put together out of the old poems. The old lays, Northern and Western, whatever their value, have all strong individual characters of their own, and do not easily submit to be regarded as merely the unused materials, waiting for an epic composer who never was born.
