What Samuel Pepys's Diary Is Actually About

2026-09-05 · Yesterself

Most people meet Samuel Pepys through two set pieces. The plague of 1665 and the Great Fire of London in 1666. Those are the passages that get quoted, and they are genuinely extraordinary. But they are a tiny fraction of what he wrote, and reading only them gives you a badly wrong idea of the book.

The diary runs from January 1, 1660 to May 31, 1669. Nine years and five months. Roughly a million and a quarter words. And the overwhelming majority of it is not history. It is a naval administrator counting his money, going to the theater when he should be working, quarreling with his wife, worrying about his eyes, buying a new coat and telling you what it cost.

That mixture is the whole point. If you want to understand why this diary survived when thousands of other seventeenth-century papers did not, the answer is not the fire. It is the coat.

What is actually in there

Pepys was a clerk who rose. In 1660 he was a nobody with a small salary and a cousin, Edward Montagu, who happened to be well placed. By the time he stopped writing he was a senior figure in the Navy Office and a man with a house, a household, and a substantial pile of cash he liked to count in private.

The daily texture of the diary reflects that life, not the life of a witness to great events. A representative stretch of entries will contain:

• Office business. Contracts for timber, masts, tar, hemp. Disputes with suppliers. What Sir William Batten said, and what Pepys thought of what Sir William Batten said. Long stretches are essentially work notes.
• Money. He counts it. Repeatedly. He records his net worth at intervals with something close to relish, and the anxiety underneath the relish is visible. He took gifts from contractors, understood perfectly well what they were, and wrote them down anyway.
• Pleasure. Plays, music, wine, walks, dinners. He was a serious amateur musician and one of the more useful early witnesses to the reopened London theaters after the Puritan closure.
• Domestic friction. His marriage to Elisabeth is on the page in ordinary, unflattering detail. Arguments about money, about her companion, about the state of the house. Reconciliations that read as genuine.
• His own conduct with women. He pursued servants and the wives of subordinates, and he recorded it, often in a private polyglot mash of Spanish, French and Latin when the subject got explicit. Modern readers find this the hardest part of the book, and they should. It is not charming. It is a man documenting behavior he knew to be wrong and doing it again the following week.
• The body. He had been cut for a bladder stone in 1658, without anesthetic, and survived. He marked the anniversary. He tracks his digestion, his colds, his fear of drafts.

The famous passages sit inside all of this without any change in register. On the morning of September 2, 1666, a maid wakes him to say there is a fire in the city. He looks at it, decides it is not much, and goes back to bed. That sentence is the diary in miniature.

Why he wrote it in shorthand

Pepys did not invent a cipher. He used Thomas Shelton's Tachygraphy, a published shorthand system that was widely taught and reasonably common among educated men of his period. It was a professional skill, the seventeenth-century equivalent of touch typing, and he had probably learned it at Cambridge.

Two things follow from that, and they pull in opposite directions.

First, the shorthand was not primarily a lock. It was speed. He often wrote entries up days after the fact, working from rough notes, and shorthand let him keep up with a life that produced a great deal of material.

Second, it did function as a soft privacy layer in practice, and he knew it. His wife could not read it. The clerks in his office could not read it. The proof is in the passages where he switches out of Shelton and into that improvised foreign-language jumble for the sexual material. If shorthand alone had felt private enough, that second layer would not exist. He was building in degrees of concealment, roughly according to how much a given sentence could cost him.

He also had the diary bound into six handsome volumes and left it, with the rest of his library, to Magdalene College, Cambridge, under instructions to keep the collection intact. That is not the behavior of a man destroying evidence. It is closer to the behavior of a man who wants to be read, eventually, by someone who is not in the room. How those volumes were turned back into English, and by whom, is a separate story.

Why he stopped

The last entry is May 31, 1669, and it is one of the saddest endings in English prose because it is not an ending at all. It is a man putting down his pen mid-life.

Pepys believed he was going blind. He had suffered for years from pain and strain in his eyes, made worse by close work in poor light, and had come to think that continuing would cost him his sight. So he stopped. He wrote that going on would be as much as seeing himself go into his grave, and he arranged for others to keep notes for him in longhand, which is a different and much thinner thing.

He did not go blind. He lived another thirty-four years, held higher office, was imprisoned twice on political suspicion, became President of the Royal Society, and died in 1703. But the diary never resumed. Elisabeth died within months of that final entry, at twenty-nine. The most intimate record we have of that marriage stops just before its worst chapter.

How to actually read it

The full text is enormous and the standard scholarly edition runs to eleven volumes. A few practical approaches:

1. Don't start at the beginning and don't start with the fire. Pick an ordinary month and read it straight through, entry by entry. April 1663, say. The point is the accumulation, and you only feel it by reading consecutive days that contain nothing.
2. Read it in daily installments if you can. The diary has circulated for years as a day-by-day feed, one entry at a time, matched to the calendar. That is closer to how it was written and it changes the experience considerably.
3. Keep the annotations nearby. Half the pleasure is in knowing who these people are, and the names come at you without introduction.
4. Let the boring parts be boring. The timber contracts are the ballast. Without them the fire is just a set piece.

What a modern writer can take from it

Two things, and neither of them is "write every day."

The first is that Pepys almost never explained himself to a future reader. He did not summarize his year, did not draw lessons, did not tidy his own character. He wrote down what happened and what it cost, in shillings where possible. That is why it holds. Interpretation ages badly. A recorded detail does not.

The second is that he wrote things he would not have wanted read at the time. The privacy was the precondition for the honesty. Take away the shorthand and you get a different, worse, more careful book.

This is the part worth borrowing, whatever you write in. Something you can be honest in first, and be seen in later, if ever, on your terms.

Yesterself is built on that order of operations. It is a journaling app where each morning brings you one letter drawn from your own past writing, and your reply that evening becomes tomorrow's mail. Entries are end-to-end encrypted, there is no account and no email address, and your identity is twelve words you hold. The server stores ciphertext it cannot read. Export is free forever, in open formats, so the archive is yours to take anywhere. It is not released yet; the waiting list on this site is the only way in for now.

Pepys got nine years and five months. He thought he was buying them at the price of his eyesight, and he was wrong about that. Whatever you keep, keep it somewhere you can still open in 2059.

Common questions

How long is Samuel Pepys's diary?

It covers nine years and five months, from January 1, 1660 to May 31, 1669, and runs to roughly 1.25 million words. The standard modern scholarly edition fills eleven volumes including the companion and index.

Why did Samuel Pepys write his diary in shorthand?

He used Thomas Shelton's Tachygraphy, a published shorthand system he had likely learned at Cambridge, mainly for speed. It also gave him a degree of privacy in practice, since his wife and his clerks could not read it.

Why did Pepys stop writing his diary?

He believed his failing eyesight would be ruined by continued close writing, so he stopped in May 1669. He did not in fact go blind, and lived another thirty-four years, but he never resumed the diary.

Is the Pepys diary only about the plague and the Great Fire?

No. Those famous passages are a small fraction of the text. Most entries concern naval office business, money, theater and music, domestic arguments, his health, and his own often unflattering personal conduct.

What is the best way to start reading the Pepys diary?

Pick an ordinary month rather than the famous events and read consecutive entries so the accumulation registers. Reading it as a daily installment, one entry per day, is also close to how it was originally written.
