From Tardis Wiki, the free Doctor Who reference
"She Walks in Beauty" was one of the works of Lord Byron. When the Thirteenth Doctor met the author while visiting Villa Diodati in 1816, she quoted "She walks in beauty, like the night. Of cloudless climes and starry skies."; prompting Byron to say that he was flattered that he was familiar with his works. (TV: The Haunting of Villa Diodati)
