William Blake, Poet & Illustrator
On the phone with Dr. Daughtery in the library, the mysterious caller, later referred to as Mr. Big (Martha Plimpton), paraphrases a line from William Blake's famous poem Tyger, Tyger, when she mentions that someone has "framed your fearful symmetry".
The line is part of a repeated stanza that opens and concludes the poem:
Tyger! Tyger! burning bright
In the forests of the night,
What immortal hand or eye
Could frame thy fearful symmetry?
