Tyger Tyger, burning bright,
In the forests of the night;
What immortal hand or eye,
Could frame thy fearful symmetry?
SONGS OF INNOCENCE AND EXPERIENCE
William Blake (28 November 1757 – 12 August 1827)
I note that Fearful Symmetry has been used as a title by, among others, Herman Northrop Frye (July 14, 1912 – January 23, 1991) on a volume of Blake criticism published in 1947 (ISBN 0-691-01291-1) and esteemed mathematician Ian Nicholas Stewart (born 24 September 1945) in 1992 (ISBN 0-631-18251-9)
