The lunatic, the lover, and the poetAre 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 forthThe forms of things unknown, the poet's penTurns them to shapes and gives to airy nothingA local habitation and a name.
William Shakespeare
beauty, illusion
