Dick Whittington’s Cat
There’s an argument on the Wikipedia page for the story of Dick Whittington and his cat about whether young Whittington could have heard the ringing of the Bow bells from Holloway. Sometimes I love Wikipedia. Also, that delightful story is a rare example of a genuine folktale arising almost in modern times – possibly as late as the early 17th century – and based on a well-known historical figure.
