She Walks in Beauty

When the Thirteenth Doctor met Lord Byron while visiting Villa Diodati in 1816, she quoted one of his poems:


 * She walks in beauty, like the night
 * Of cloudless and starry skies

This prompted Byron to say that he was flattered that she was familiar with his works. (TV: The Haunting of Villa Diodati)
