An Animal, no bigger than a Mite, cannot appear perfect to the Eye, because the Sight takes it in at once, and has only a confused Idea of the Whole, and not a distinct Idea of all its Parts; if on the contrary you should suppose an Animal of ten thousand Furlongs in length, the Eye would be so filled with a single Part of it, that it could not give the Mind an Idea of the Whole. What these Animals are to the Eye, a very short or a very long Action would be to the Memory. The first would be, as it were, lost and swallowed up by it, and the other difficult to be contained in it.
Homer
Virgil
have shewn their principal Art in this Particular; the Action of the
Iliad
, and that of the
Æneid
, were in themselves exceeding short, but are so beautifully extended and diversified by the
Invention
