The defect of the Northern epic is that it allowed itself to be too soon restricted in its scope. It became too minute, too emphatic, too intolerant of the comfortable dilutions, the level intervals, between the critical moments.[39] It was too much affected by the vanities of the rival Scaldic poetry; it was overcome by rhetoric. But it cannot be said that it went out tamely. [Footnote 39: There is a natural affinity to Gray's poetry in the Icelandic poetry that he translated--compressed, emphatic, incapable of laxity.] VI _BEOWULF_ The poem of _Beowulf_ has been sorely tried; critics have long been at work on the body of it, to discover how it is made. It gives many openings for theories of agglutination and adulteration. Many things in it are plainly incongruous. The pedigree of Grendel is not authentic; the Christian sentiments and morals are not in keeping with the heroic or the mythical substance of the poem; the conduct of the narrative is not always clear or easy to follow. These difficulties and contradictions have to be explained; the composition of the poem has to be analysed; what is old has to be separated from what is new and adventitious; and the various senses and degrees of "old" and "new" have to be determined, in the criticism of the poem. With all this, however, the poem continues to possess at least an apparent and external unity. It is an extant book, whatever the history of its composition may have been; the book of the adventures of Beowulf, written out fair by two scribes in the tenth century; an epic poem, with a prologue at the beginning, and a judgment pronounced on the life of the hero at the end; a single book, considered as such by its transcribers, and making a claim to be so considered.
