Key takeaways
- The reliable Leonardo da Vinci quotes come from his notebooks, and every line below is checked against Jean Paul Richter's 1888 English edition, with its section number.
- Several of the most shared "Leonardo quotes," including "Simplicity is the ultimate sophistication," have no traceable source in the Richter edition.
- Some popular lines are loose rewrites of real passages: "Fix your course on a star" grows out of "He who is fixed to a star does not change his mind."
- Leonardo wrote his notes in mirror script, from right to left, which is one reason so few people read the originals.
- His best lines are about experience, time and work, and most of them are short enough to remember.
About five thousand pages of Leonardo da Vinci's manuscripts survive, by his translator's count, and very few people quoting him have read any of them. The result is a large body of "Leonardo quotes" that sound right, get shared constantly, and cannot be found in his writing.
This list works from the notebooks themselves. Every quote is given in the wording of Jean Paul Richter's translation, published in 1888 and freely available through Project Gutenberg, with Richter's section number so you can find it yourself.
Where do Leonardo da Vinci quotes come from?
Genuine Leonardo quotes come from his notebooks, which mix sketches, diagrams and notes on painting, anatomy, water, machines and life. The Victoria and Albert Museum, which holds five of his notebooks bound into three volumes known as the Forster Codices, describes them as annotated in Italian mirror writing that reads from right to left.
Richter's edition is the standard way into them in English. His preface explains that he arranged passages from the scattered manuscripts by subject and numbered them from 1 to 1566. Section numbers below refer to that edition.
The man himself is easier to summarize. The National Gallery notes he was born near the Tuscan hill town of Vinci, was raised by his paternal grandfather, and left many works unfinished, yet was revered as a universal genius.
What are the best real Leonardo da Vinci quotes?
The best real Leonardo da Vinci quotes are short maxims on experience, time and judgment, most of them grouped under philosophical maxims and morals in Richter's second volume.
"Wisdom is the daughter of experience." (Section 1150)
"Truth was the only daughter of Time." (Section 1152)
"Experience never errs; it is only your judgments that err by promising themselves effects such as are not caused by your experiments." (Section 1153)
"Science is the captain, and practice the soldiers." (Section 1160)
"Avoid studies of which the result dies with the worker." (Section 1169)
"As a day well spent procures a happy sleep, so a life well employed procures a happy death." (Section 1173)
"Life if well spent, is long." (Section 1174)
"The water you touch in a river is the last of that which has passed, and the first of that which is coming. Thus it is with time present." (Section 1174)
"When Fortune comes, seize her in front with a sure hand, because behind she is bald." (Section 1177)
"The greatest deception men suffer is from their own opinions." (Section 1180)
"He is a poor disciple who does not excel his master." (Section 498)
The punctuation is Richter's, including the comma in "Life if well spent, is long." The river passage is worth reading twice. It is a description of the present moment that a physicist would not argue with.
Which popular Leonardo quotes are not in his notebooks?
Several of the most shared lines have no traceable source in the Richter edition, and others are modern rewrites of real passages. The table puts the popular version beside what Richter actually prints.
| Popular version | What the Richter edition has | Where it comes from |
|---|---|---|
| "Simplicity is the ultimate sophistication" | No traceable source | Not found in Richter |
| "Art is never finished, only abandoned" | No traceable source | Not found in Richter |
| "I love those who can smile in trouble" | No traceable source | Not found in Richter |
| "Fix your course on a star and you'll navigate any storm" | "He who is fixed to a star does not change his mind" | Section 682 |
| "Iron rusts from disuse" | "Just as iron rusts unless it is used, and water putrifies or, in cold, turns to ice, so our intellect spoils unless it is kept in use" | Section 1177 |
| "Poor is the pupil who does not surpass his master" | "He is a poor disciple who does not excel his master" | Section 498 |
The star line is the most interesting rewrite. Section 682 is a short motto written beside two sketches: "Obstacles cannot crush me / Every obstacle yields to stern resolve / He who is fixed to a star does not change his mind." It is about steadiness. The popular version turns it into navigation advice, and adds a storm Leonardo never mentioned.
Did Leonardo say "simplicity is the ultimate sophistication"?
There is no traceable source for it in the Richter edition. A search of the full text for "simplicity," "sophistication" and related stems turns up only Richter's own editorial notes and technical terms such as "simple perspective" and "simple shadow," never a maxim of this kind.
That finding is deliberately narrow. Richter's 1,566 passages are drawn from roughly five thousand surviving pages, so absence there is not proof he never wrote it. But a quote this famous with no codex, folio or section number attached should be treated as unsourced, and that is how it is listed here. The same goes for "Art is never finished, only abandoned" and "I love those who can smile in trouble."
Why did Leonardo write backwards?
Nobody knows for certain, and the Victoria and Albert Museum lays out both main theories. One is that he wanted to keep his notes private. The other is simpler: he was left-handed and may have found right-to-left writing easier.
The museum adds two details that point away from the secrecy idea. It notes that writing masters of the period demonstrated mirror writing, and that his letter shapes are ordinary, the kind of script his father, a notary, would have used. Once your eye adjusts, the museum says, it can be read.
Mirrors also turn up in his advice to painters. In section 530 he tells them to check a painting in a flat mirror, where it looks reversed, like another painter's work, so its faults are easier to judge.
What did Leonardo write about painting and work?
He wrote that theory has to come before practice, and that a painter should step away from the work regularly. Both points are made bluntly.
In section 19: "Those who are in love with practice without knowledge are like the sailor who gets into a ship without rudder or compass and who never can be certain whether he is going." In section 530: "it is well that you should often leave off work and take a little relaxation, because, when you come back to it you are a better judge."
He also defended painting against poetry with real heat. Section 653 calls the eye "the window of the soul" and answers the old jibe about silent pictures: "if you call painting dumb poetry, the painter may call poetry blind painting."
How can you check a Leonardo quote yourself?
Ask for a reference before you trust a line, then look it up. A few rules cover almost every case:
- Look for a section number, codex name or folio. A quote with none of these has not been checked by whoever posted it.
- Search Richter's text on Project Gutenberg for a distinctive word, not the whole sentence, because translations differ.
- Try the older vocabulary: "disciple" for pupil, "excel" for surpass, "employed" for used.
- If the line sounds like modern business advice, be suspicious. Leonardo wrote in images (rivers, stars, iron, fortune), not slogans.
- Phrase any negative finding carefully: "not found in Richter," not "fake."
Which Leonardo imagery works on a wall?
A short maxim or a portrait both work, and the portrait does not need a caption. "Wisdom is the daughter of experience" reads in a glance, which is the test for any line you will see every day.
Da Vinci Amplified takes the portrait route. It paints Leonardo in his dark cap and robe, holding up a speaker blueprint in the style of his notebook drawings beside a speaker cabinet, as if the cross-section were one more invention on the page. It is one gallery-wrapped canvas on a solid pine frame, ready to hang and made to order in Europe, with a floating frame as an optional upgrade.
It belongs to a series of painted figures in the historical figure wall art collection, alongside Bach, Mozart and Marie Antoinette. For choosing words to live with, see how to choose quote wall art that means something, and for the room it would hang in, our home office wall art guide.

Frequently asked questions
What is Leonardo da Vinci's most famous quote?
One of the lines most often credited to him, "Simplicity is the ultimate sophistication," has no traceable source in Richter's edition of the notebooks. Among verified lines, "Wisdom is the daughter of experience" (section 1150) and "Life if well spent, is long" (section 1174) are short enough to quote anywhere.
Where can I read Leonardo's notebooks in English?
Jean Paul Richter's 1888 translation is free on Project Gutenberg. It arranges passages by subject, from perspective and painting to philosophy, and numbers each one, so any quote with a section number can be checked in seconds.
Did Leonardo da Vinci say "art is never finished, only abandoned"?
There is no traceable source for it in the Richter edition of his notebooks. It may come from somewhere else entirely, but no section, codex or folio is usually given with it, so it is best treated as unsourced rather than as Leonardo's words.
Why are Leonardo's notebooks written backwards?
He wrote in mirror script, from right to left. The Victoria and Albert Museum notes that he may simply have found it easier as a left-hander, and that his letter shapes were ordinary, which argues against the idea of a secret code.
Is "iron rusts from disuse" a real Leonardo quote?
It is a shortened version of a real passage. Section 1177 in Richter reads "Just as iron rusts unless it is used, and water putrifies or, in cold, turns to ice, so our intellect spoils unless it is kept in use."
