TELL me where is Fancy bred,
Or in the heart or in the head?
How begot, how nourished?
   Reply, reply.
It is engender’d in the eyes,
With gazing fed; and Fancy dies
In the cradle where it lies.
   Let us all ring Fancy’s knell:
   I’ll begin it,–Ding, dong, bell.
All. Ding, dong, bell.

William Shakespeare
