I deny this altogether. "The improbability" might be "grosser" if the Iliad had been composed in a day! But if, as any man of common sense would acknowledge, it was composed in parts or "fyttes" of moderate length at a time, no extraordinary power of memory, or tension of thought, would have been required by the poet. Such parts, once recited and admired, became known and learned by a hundred professional bards, and were thus orally published, as it were, in detached sections, years perhaps before the work was completed. All that is said, therefore, about the difficulty of composing so long a poem without writing materials is but a jargon of words. Suppose no writing materials existed, yet, as soon as portions of a few hundred lines at a time were committed to the memory of other minstrels, the author would, in those minstrels, have living books whereby to refresh his memory, and could even, by their help, polish and amend what was already composed. It would not then have been necessary for the poet himself perfectly and verbally to remember the whole work. He had his tablets of reference in the hearts and lips of others, and even, if it were necessary that he himself should retain the entire composition, the constant habit of recital, the constant exercise of memory, would render such a task by no means impracticable or unprecedented. As for the unity of the poem, thus composed, it would have been, as it is, the unity, not of technical rules and pedantic criticism, but the unity of interest, character, imagery, and thought--a unity which required no written references to maintain it, but which was the essential quality of one master-mind, and ought to be, to all plain men, an irrefragable proof that one mind alone conceived and executed the work.
