Now, what these wicked spirits cannot compass, by the vast disproportion of their forces to those of the superior beings, they may, by their fraud and cunning, carry farther, in a seeming league, confederacy, or subserviency to the designs of some good angel, as far as consists with his purity to suffer such an aid, the end of which may possibly be disguised, and concealed from his finite knowledge. This is, indeed, to suppose a great error in such a being: yet since a devil can appear like an angel of light; since craft and malice may sometimes blind, for a while, a more perfect understanding; and, lastly, since Milton has given us an example of the like nature, when Satan, appearing like a cherub to Uriel, the intelligence of the sun, circumvented him even in his own province, and passed only for a curious traveller through those new-created regions, that he might observe therein the workmanship of God, and praise him in his works,--I know not why, upon the same supposition, or some other, a fiend may not deceive a creature of more excellency than himself, but yet a creature; at least, by the connivance, or tacit permission, of the Omniscient Being. Thus, my lord, I have, as briefly as I could, given your lordship, and by you the world, a rude draught of what I have been long labouring in my imagination, and what I had intended to have put in practice, (though far unable for the attempt of such a poem,) and to have left the stage, (to which my genius never much inclined me,) for a work which would have taken up my life in the performance of it. This, too, I had intended chiefly for the honour of my native country, to which a poet is particularly obliged. Of two subjects, both relating to it, I was doubtful whether I should choose that of King Arthur conquering the Saxons, which, being farther distant in time, gives the greater scope to my invention; or that of Edward, the Black Prince, in subduing Spain, and restoring it to the lawful prince, though a great tyrant, Don Pedro the Cruel: which, for the compass of time, including only the expedition of one year; for the greatness of the action, and its answerable event; for the magnanimity of the English hero, opposed to the ingratitude of the person whom he restored; and for the many beautiful episodes, which I had interwoven with the principal design, together with the characters of the chiefest English persons; (wherein, after Virgil and Spenser, I would have taken occasion to represent my living friends and patrons of the noblest families, and also shadowed the events of future ages, in the succession of our imperial line,)--with these helps, and those of the machines, which I have mentioned, I might perhaps have done as well as some of my predecessors, or at least chalked out a way for others to amend my errors in a like design; but being encouraged only with fair words by King Charles II., my little salary ill paid, and no prospect of
