From Richard Horton
Jonathon Keats, reviewing Time Travel: A history, states that “only since the 20th century have we sought ways to communicate with the future” (10 September, p 42). Those of us who survey churchyards and record memorial inscriptions know that this desire goes back much further. Here, for example, is part of an inscription in St John's Kirkheaton, West Yorkshire, clearly addressed to future readers: “… Also of Sarah daughter of the above named Mark and Ann Fisher… What we are now so you must be, therefore prepare to follow me.”
