It is probable, that, when Dryden abandoned all thoughts of a larger work, he adapted the intended subject to the following opera, and converted the Genii of the kingdoms, by whom the supernatural machinery of the epic was to have been conducted, into the lighter and simpler device of airy and earthy spirits, whose idea the Rosicrucian philosophy had long rendered popular and familiar. There is no attempt to avail himself of any fragments of Arthur's romantic renown. He is not, in this drama, the formidable possessor of Excalibar, and the superior of the chivalry of the Round Table; nor is Merlin the fiend-born necromancer, of whom antiquity related and believed so many wonders. They are the prince and magician of a beautiful fairy tale, the story of which, abstracted from the poetry, might have been written by Madame D'Aunois. At the same time, the obvious advantages of an appeal to the ancient prejudices, which our author has neglected, are supplied from the funds of his own genius. The incidents, being intended more for the purpose of displaying machinery, and introducing music and dances, than with any reference to the rules of the drama, are abundantly fantastic and extravagant; but the poet has supported them with wonderful address. The blindness of Emmeline, and the innocence with which she expresses her conception of visible objects, gives her character an interest often wanting in what may be called the heroine of a play, whose perfections generally raise her so far beyond mere mortal excellence, as to render superfluous all human sympathy. The scene in which Emmeline recovers her sight, when well represented, never fails to excite the most pleasing testimony of interest and applause. The machinery is simple, and well managed: the language and ministry of Grimbald, the fierce earthy dæmon, are painted with some touches which arise even to sublimity. The conception of Philidel, a fallen angel, retaining some of the hue of heaven, who is touched with repentance, and not without hope of being finally received, is an idea, so far as I know, altogether original. Klopstock has since introduced a similar character into sacred poetry[10]. The principal incident in "King Arthur" is copied, in almost every circumstance, from the adventures of Rinaldo in the haunted grove on Mount Olivet[11], which makes also the subject of an Italian opera.
