The Tyger

From Tardis Wiki, the free Doctor Who reference

The Tyger[1] was a poem written by William Blake, and considered to be one of his most famous works.

After Tommy looked into the Metebelis crystal and realised he could now read much better, he went to get more books from the meditation centre's library. There he found a book of poetry which included The Tyger, and proceeded to read the opening verse aloud:

Tyger Tyger, burning bright,
In the forests of the night;
What immortal hand or eye,
Could frame thy fearful symmetry?

Tommy called the poem "pretty" before correcting himself to "beautiful". (TV: Planet of the Spiders)
