Method & creation
Why are so many of Leonardo da Vinci's works unfinished?
Rushed departures, overly ambitious projects, experimental techniques and endless improvement: Leonardo's unfinished business never has a single cause.
Short answer
Leonardo begins as a researcher, not a hasty performer
His works remain unfinished when an order is interrupted, a patron changes priority, a war disperses the site or the painter constantly transforms his project. His taste for experience and observation also slows down execution: each painting becomes a laboratory of light, anatomy, movement and matter.
Change city
Leonardo leaves Florence for Milan, leaving theAdoration of the Magi at a preparatory stage.
Change the project
It uses drawings, poses and effects instead of mechanically following a fixed model.
Test the material
Its wall or technical tests can produce fragile results that are difficult to continue.
Refuse closure
Some paintings stay with him for years, constantly perfected.
Florence · 1481 -1482
Adoration of the Magi: a departure interrupts the command
The Augustinians of San Donato a Scopeto commissioned Leonardo to create a large altarpiece which he promised to complete in thirty months. He organizes around the Virgin a crowd in a semi-circle, horsemen, ruins and gestures that respond to each other.
But he leaves Florence for Milan. The work remains at the stage of advanced construction: some figures are only indications, others are modeled, the white background and brown layers show the stages of thought.
He is therefore not only a painter "incapable of finishing": a change of career and patronage materially cuts off the construction site. The monks wait in vain, then order another altarpiece from Filippino Lippi.
Around 1481 -1482
Saint Jerome: the process remains visible
The Vatican painting shows several degrees of advancement. The saint's torso and head are powerfully shaped, while the landscape, lion and other areas remain largely preparatory.
The incompleteness reveals the way Leonardo progresses: drawing, shadows, paint passages and glazes are not applied uniformly over the entire surface. The Vatican Museums even report the use of fingers to soften certain transitions.
We do not know the exact cause of the shutdown. No documented order can tell of a break as clear as for theWorship. We must therefore distinguish the material observation - the picture is unfinished - from a story that the sources do not allow us to reconstruct.
What the surface shows
Five steps can coexist in the same table
Quick strokes to place masses.
Contours and repentances organize the figures.
A colored layer unifies the support.
Shadows and lights give volume.
Thin layers nuance the transitions.
Three types of incompleteness
Abandoned, interrupted or still reworked
Project prevented
The Sforza equestrian monument reaches the stage of a huge clay model. The bronze intended for melting was requisitioned to make cannons, then the model was destroyed after the fall of Milan.
Vulnerable technique
The Last Supper is completed, but his dry technique begins to deteriorate very early. Unfinished work should not be confused with completed work that has become incomplete.
Work constantly repeated
Leonardo kept several paintings with him. There Mona Lisa illustrates a painting matured over a long period of time, even if simply describing it as "unfinished" remains reductive.
Around 1503 -1519
Saint Anne: ten years of research and a work still open
The Louvre painting was begun in Florence, preserved by Leonardo and continued slowly until the end of his life. Analyzes and preparatory drawings show that the composition was not born in a single draft: the painter moves the figures, modifies the draperies and deepens the landscape.
The Louvre describes it as still unfinished in 1519. However, the image seems very accomplished to the visitor. This is a good reminder: incompleteness can concern particular passages, the degree of finish desired by the artist or the absence of a definitive stop, without making the work illegible.
For Leonardo, finishing is not just filling the entire surface. It's solving a set of visual problems - and each solution can give rise to a new one.
The role of context
Wars and patrons weigh as much as perfectionism
The bronze from the Sforza monument is used for armament. Then the French invasion overthrew Ludovico the More and dispersed the court.
La Battle of Anghiari mobilizes a huge project. Leonardo only completed part of it before leaving for Milan.
Major commissions go mainly to Michelangelo and Raphael. Leonardo continues research and experiments without producing a vast completed cycle.
Comparison
Why does every work stop?
| Work or project | Date | State | Known main cause | What the unfinished reveals |
|---|---|---|---|---|
| Adoration of the Magi | 1481 - 1482 | Very advanced preparatory painting | Departure from Florence for Milan | Crowd building and repentance |
| Saint Jerome | Around 1481 -1482 | Very different finishing degrees | Specific cause unknown | Drawing, fingers, modeling and glazing |
| Sforza Monument | Around 1487 -1499 | Clay model, bronze never cast | Bronze requisitioned then fall of Milan | Engineer and sculptor ambition |
| Battle of Anghiari | 1503 -1506 | Decor partially executed, now lost | Technique, scale and recall in Milan | Studies of movement and fury |
| Saint Anne | Around 1503 -1519 | Very accomplished but still unfinished | Prolonged improvement until death | Successive revisions and layers |
Another idea of the work
The unfinished becomes an exceptional document
A completely finished painting often hides its stages. In Leonardo, interrupted works reveal changes of idea, the transition from drawing to painting and modeling methods. That's why Saint Jerome and theAdoration of the Magi today are crucial sources on his work - not failures relegated to the background.
A displaced head or an abandoned outline proves that the composition evolves directly on the support.
Brush marks, friction and fingerprints provide information on concrete manufacturing.
Open areas allow you to follow the hierarchy of problems that Leonardo chooses to solve.

Frequently asked questions
Did Leonardo da Vinci rarely finish his paintings?
His painted corpus is small and several major projects are unfinished, but he has also delivered successful works. The reputation comes above all from the exceptional importance of the interrupted projects.
Why is the Adoration of the Magi unfinished?
Leonardo left Florence for Milan around 1482 before completing the altarpiece commissioned by the monks of San Donato a Scopeto.
Was Saint Jerome a command?
No decisive document can identify with certainty the sponsor or the reason for the abandonment. Its material state is certain, its initial history is much less so.
Is the Mona Lisa unfinished?
It was reworked and preserved at length by Leonardo. Some authors speak of a work never definitively closed, but it presents a degree of completion very different from Saint Jerome or Adoration.
Is the Last Supper unfinished?
No: it was completed around 1498. Its incomplete appearance comes from the rapid degradation of a fragile wall technique and centuries of intervention.
Was the unfinished intentional?
Sometimes Leonardo agrees to leave a work open to take it up again. But several abandonments clearly result from external circumstances. There is no single theory valid for all cases.
