After a short mid-season break, Paul and Miranda return with a timely exploration of 17th-century diaries. This was the century in which the habit of keeping daily personal reflections became widespread - perhaps because, for some devout Protestants, diaries replaced the confessional as a medium in which to confide their innermost thoughts. Greater literacy also contributed to the diary boom.

Miranda and Paul revisit the wonderfully revealing diaries of genre superstars Samuel Pepys and John Evelyn, whose entries often juxtaposed the dramatic with the mundane. They also explore some lesser-known exponents of the art, such as Celia Fiennes, who visited every county in England on horseback and kept a daily record of her journeys for posterity. All human life is here - while some diarists laid bare the progress of the century's many conflicts, others used their diaries as a place to log recipes.

'1666 and All That' is presented by Paul Lay and Miranda Malins. The producer is Hugh Costello. Original music is by George Taylor. The episode is mixed by Sam Gunn.
