There is an untraceable moment at which the past slips from the realm of memory into deep time. Perhaps it is around the 100-year mark, when those who witnessed any given event have long since died. Just occasionally, technology offers a way down the rabbit hole. There exists, for instance, an 1890 recording of the poet Alfred, Lord Tennyson reciting “The Charge of the Light Brigade”, his response to the account in the Times of that tragic manoeuvre. There are also two recordings, from 1902 and 1904, of the castrato Alessandro Moreschi, a member of the Sistine Chapel Choir for 30 years and one of the last boys to be mutilated for choral fodder.
