But the gravest difficulty, and perhaps the most important, in poetry meant solely for recitation, is the difficulty of achieving verbal beauty, or rather of making verbal beauty tell.
There is only one thing which can master the perplexed stuff of epic material into unity; and that is, an ability to see in particular human experience some significant symbolism of man's general destiny.
Traditional matter must be glorified, since it would be easier to listen to the re-creation of familiar stories than to quite new and unexpected things; the listeners, we must remember, needed poetry chiefly as the re-creation of tired hours.
The Border Ballads, for instance, and the Robin Hood Ballads, clearly suppose a state of society which is nothing but a very circumscribed and not very important heroic age.
An epic is not made by piecing together a set of heroic lays, adjusting their discrepancies and making them into a continuous narrative.
But the development of human society does not go straight forward; and the epic process will therefore be a recurring process, the series a recurring series - though not in exact repetition.

No poet will ever take the written word as a substitute for the spoken word; he knows that it is on the spoken word, and the spoken word only, that his art is founded.
Poetry is the work of poets, not of peoples or communities; artistic creation can never be anything but the production of an individual mind.

The epic poet collaborates with the spirit of his time in the composition of his work. That is, if he is successful; the time may refuse to work with him, but he may not refuse to work with his time.
The epic poet has behind him a tradition of matter and a tradition of style; and that is what every other poet has behind him too; only, for the epic poet, tradition is rather narrower, rather more strictly compelling.
The first epics were intended for recitation; the literary epic is meant to be read.
