The “State of Innocence” seems to have been undertaken by Dryden during a cessation of his theatrical labours, and was first published in 1674, shortly after the death of Milton, which took place on the 8th of November in the same year.

   Vol.  I. the elegant Hayley’s Conjectures on the Origin of Paradise
   Lost, and Walker’s Memoir on Italian Tragedy.  The Drama of Andreini
   opens with a grand chorus of angels, who sing to this purpose: 

     Let the rainbow be the fiddle-stick to the fiddle of heaven,
     Let the spheres be the strings, and the stars the musical notes;
     Let the new-born breezes make the pauses and sharps,
     And let time be careful to beat the measure.

TO

HER ROYAL HIGHNESS,

THE

DUCHESS[1].

MADAM,

Ambition is so far from being a vice in poets, that it is almost impossible for them to succeed without it.  Imagination must be raised, by a desire of fame, to a desire of pleasing; and they whom, in all ages, poets have endeavoured most to please, have been the beautiful and the great.  Beauty is their deity, to which they sacrifice, and greatness is their guardian angel, which protects them.  Both these, are so eminently joined in the person of your royal highness, that it were not easy for any but a poet to determine which of them outshines the other.  But I confess, madam, I am already biassed in my choice.  I can easily resign to others the praise of your illustrious family, and that glory which you derive from a long-continued race of princes, famous for their actions both in peace and war:  I can give up, to the historians of your country, the names of so many generals and heroes which crowd their annals, and to our own the hopes of those which you are to produce for the British chronicle.  I can yield, without envy, to the nation of poets, the family of Este, to which Ariosto and Tasso have owed their patronage, and to which the world has owed their poems.  But I could not, without extreme reluctance, resign the theme of your beauty to another hand.  Give me leave, madam, to acquaint the world, that I am jealous of this subject; and let it be no dishonour to you, that, after having raised the admiration of mankind, you have inspired one man to give it voice.  But, with whatsoever vanity this new honour of being your poet has filled my mind, I confess myself too weak for the inspiration:  the priest was always unequal to the oracle:  the god within him was too mighty for his breast:  he laboured with the sacred revelation, and there was more of the mystery left behind, than the divinity itself could enable him to express.  I can but discover a part of your excellencies to the world;
