The Diary of Samuel Pepys It was in this house that Pepys started to write his diary, at the age of 27. He was 36 when fear of losing his eyesight forced him to end it. In June 1660 he was appointed Clerk of the Acts to the Navy Board, a key post in what was probably the most important of all government departments - the royal dockyards. epys's diary is not so much a record of events as a re-creation of them. Not all the passages are as picturesque as the famous set pieces in which he describes Charles II's coronation or the Great Fire of London, but there is no entry which does not, in some degree, display the same power of summoning back to life the events it relates.
