Hazlitt says, one cannot "make an allegory go on all fours," it must to a certain degree be obscure and shadowy, like the images which the traveller in the desert sees mirrored on the heavens, wherein he can trace but a dreamy resemblance to the reality beneath. It therefore seems to me advisable to give a solution of the "Eidolon," the symbol, which follows, that the purpose of the poem may at once be evident.
