The lunatic, the lover, and the poet Are of imagination all compact. One sees more devils than vast hell can hold; That is the madman. The lover, all as frantic, Sees Helen's beauty in a brow of Egypt. The poet's eye, in a fine frenzy rolling, Doth glance from heaven to earth, from earth to heaven; And as imagination bodies forth The forms of things unknown, the poet's pen Turns them to shapes, and gives to airy nothing A local habitation and a name.
