We now try to show that the Epics present an historical unity, a complete and harmonious picture of an age, in its political, social, legal, and religious aspects; in its customs, and in its military equipment. A long epic can only present an unity of historical ideas if it be the work of one age. Wandering minstrels, living through a succession of incompatible ages, civic, commercial, democratic, could not preserve, without flaw or failure, the attitude, in the first place, of the poet of feudal princes towards an Over-Lord who rules them by undisputed right divine, but rules weakly, violently, unjustly, being subject to gusts of arrogance, and avarice, and repentance. Late poets not living in feudal society, and unfamiliar alike with its customary law, its jealousy of the Over-Lord, its conservative respect for his consecrated function, would inevitably miss the proper tone, and fail in some of the many [blank space] of the feudal situation. This is all the more certain, if we accept Mr. Leaf's theory that each poet-rhapsodist's _repertoire_ varied from the _repertoires_ of the rest. There could be no unity of treatment in their handling of the character and position of the Over-Lord and of the customary law that regulates his relations with his peers. Again, no editor of 540 B.C. could construct an harmonious picture of the Over-Lord in relation to the princes out of the fragmentary _repertoires_ of strolling rhapsodists, which now lay before him in written versions. If the editor could do this, he was a man of Shakespearian genius, and had minute knowledge of a dead society. This becomes evident when, in place of examining the _Iliad_ through microscopes, looking out for discrepancies, we study it in its large lines as a literary whole. The question being, Is the _Iliad_ a literary whole or a mere literary mosaic? we must ask "What, taking it provisionally as a literary whole, are the qualities of the poet as a painter of what we may call feudal society?" Choosing the part of the Over-Lord Agamemnon, we must not forget that he is one of several analogous figures in the national poetry and romance of other feudal ages. Of that great analogous figure, Charlemagne, and of his relations with his peers in the earlier and later French mediaeval epics we shall later speak. Another example is Arthur, in some romances "the blameless king," in others _un roi faineant_. The parallel Irish case is found in the Irish saga of Diarmaid and Grainne. We read Mr. O'Grady's introduction on the position of Eionn Mac Cumhail, the legendary Over-Lord of Ireland, the Agamemnon of the Celts. "Fionn, like many men in power, is variable; he is at times magnanimous, at other times tyrannical and petty. Diarmaid, Oisin, Oscar, and Caoilte Mac Rohain are everywhere the [Greek: kaloi kachotoi] of the Fenians; of them we never hear anything bad."
