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.
