Gustave Moreau, Jupiter and Semele, 1894

Gustave Moreau

1826–1898 · France

Researched by Daniel Bilmes, painter and educator.

Gustave Moreau taught by liberating each student's temperament. As a professor at the Ecole des Beaux-Arts from 1892 to 1898, he guided pupils like Henri Matisse and Georges Rouault not by imposing his own Symbolist style but by pressing them to find their own. His method had two pillars: first, the rigorous academic study of drawing and painting from casts and the live model; second, the study of Old Masters in the Louvre to find a personal lineage. Moreau held that art was a cosa mentale, a thing of the mind, and urged students to trust their inner world. He famously told Matisse "You will simplify painting," and Matisse later said Moreau "disturbed our complacency." His students revered him as "The Liberator" for giving them both the tools and the freedom that shaped 20th-century painting.

Signature moves

Teach to liberate, not to replicate

Refused to impose his own style, seeking instead to wake the individual temperament of each student, which earned him the posthumous title "The Liberator."

Why it matters · Most academic masters made disciples. Moreau made individuals. By withholding a formula, he forced students like Matisse and Rouault to build their own, which set up the revolutions of 20th-century painting.

Georges Rouault, Souvenirs intimes, on Moreau's "constant care to respect the individual personality", 1926

Send students to the Louvre to find their own ancestors

Sent students to study and freely interpret the Old Masters in the Louvre, not to copy them, but to discover their own artistic lineage.

Why it matters · Moreau knew originality does not come from nowhere. Connecting students to the deep past gave them a foundation to build on and to push against, so they found a place in a lineage rather than merely following a living teacher.

Albert Marquet: The Paradox of Time, on Moreau's advice to freely interpret a favourite masterpiece

Put the inner world first (cosa mentale)

Taught that art was a cosa mentale, a thing of the mind, and that what the artist feels matters more than what the artist sees.

Why it matters · This broke with the observational focus of both academic and Impressionist painting. It gave students permission to use colour and form to carry feeling, a founding principle of the Fauvism and Expressionism they would go on to make.

Disturb their complacency

Corrected not by handing down rules but by provoking students to find their own answers, a method Matisse described as being set "off the roads."

Why it matters · An easy answer stops a student thinking. A hard question forces them to build their own judgment. Moreau's provocations grew his students' independence of mind and hand.

Henri Matisse, quoted in H. Spurling, The Unknown Matisse

Correct with paternal encouragement

Took students aside for private, encouraging critiques, a style his student Henri Evenepoel called "paternal and encouraging, and at the same time very just."

Why it matters · In the often harsh, competitive world of the Ecole, Moreau made a place of safety. That support was what allowed the risk-taking and experiment his liberating philosophy asked for.

In the studio

Studio

Light: The official, light-filled painting atelier at the Ecole des Beaux-Arts on the Rue Bonaparte, and his own home and studio at 14 rue de La Rochefoucauld for informal Sunday receptions.
Position: As chef d'atelier he corrected student work at their easels twice a week. He once climbed the five flights to Henri Matisse's studio to encourage him after a failed competition.
Session length: Corrections on Wednesdays and Saturdays from 1892 to 1898, about three hours each. The official studio hours ran 8 a.m. to noon and 1 p.m. to 4 p.m.
Tools: The Ecole's collection of plaster casts of classical sculpture for drawing · The live model, whose fee the students paid themselves · His vast personal archive of engravings, photographs, and reproductions, used as a teaching resource on Sunday visits
Notes: The atelier was a hierarchical room run day to day by a senior student, the massier (a role held by Georges Rouault). Tuition was free, but students paid for the model, heating, and their own materials. Moreau split his teaching between these formal sessions and Sunday gatherings at his home, which was being turned into the future Musee Gustave Moreau.

Palette

Ground: Students supplied their own: sketch paper, tinted papers (cream or blue-grey), and commercially prepared canvases.
Whites: White chalk for drawing
Earths: Red chalk (sanguine) and charcoal for the drawing studies
Blacks: Charcoal, black stone, and black pencil for drawing
Medium: This record describes Moreau's teaching atelier, not his personal Symbolist practice. Students worked in the standard academic drawing media (charcoal and chalks) and in oil. Specific pigments are not documented and were each student's own choice and expense.
Quantity: Not applicable to a teacher overseeing student work.

Workflow, from blank canvas

1. Draw from casts and engravings
Begin by copying plaster casts of classical sculpture and engravings of Old Master works to master line and form.
Why: This foundational step builds drawing skill on idealised, static forms before the complexity of the live model.
2. Draw from the live model
After the master's approval, progress to drawing from the live model, the central exercise of the atelier.
Why: Carrying the principles learned from casts onto the living figure is the bridge from idealised form to observed representation.
3. Paint the academy
Make a painted study from a single model pose, often a full week from lay-in to finish.
Why: This was the primary exercise for learning to turn observed form, light, and shadow into oil paint.
4. Study and interpret the masters
Go to the Louvre to find and freely interpret a masterpiece, taking its lessons in composition, colour, and mood.
Why: Moreau held that this was how a student found their own lineage and voice, by entering a dialogue with the past.
5. Develop personal compositions
Use the acquired skill and historical study to make original works carrying an inner vision, a cosa mentale.
Why: This was the aim of his teaching: give students the tools of the academy, then set them free to paint their own imagination.

Refusals — what they would not do

Refused to impose his own style, aiming to liberate his students rather than make disciples.
Refused to put literal observation first, telling students to believe in what they felt over what they saw.
Refused to hand out a formula or easy answers, choosing to disturb their complacency with questions.
Refused to let academic training be an end in itself, treating it instead as the means to imaginative freedom.

Reference

Primary source: The live model and the Ecole's collection of plaster casts of classical sculpture were the primary references for in-atelier exercises.
Photography: Moreau kept a personal collection of photographs that served as a supplemental resource for students during visits to his home.

Exceptions

The Old Masters in the Louvre were a central reference, which Moreau directed students to study and freely interpret as a core part of their training.

George Desvallieres and Rene Piot, who both testified to the intellectual and spiritual guidance Moreau gave.

In their own words

“He did not set us on the right roads, but off the roads. He disturbed our complacency.”

— Henri Matisse, Quoted in H. Spurling, The Unknown Matisse

Matisse on how Moreau's teaching provoked students to find their own way rather than follow a prescribed path.

“I believe neither in what I touch nor what I see. I only believe in what I do not see, and solely in what I feel.”

Questions and answers

Who did Gustave Moreau teach?

Moreau taught 125 pupils at the Ecole des Beaux-Arts between 1892 and 1898. His most famous students, who formed the core of the Fauvist movement, were Henri Matisse, Georges Rouault, and Albert Marquet.

What was Gustave Moreau's teaching philosophy?

It was one of liberation. He did not want copies of himself. He taught academic fundamentals but pressed students to put their inner imagination first, what he called a cosa mentale, and to study the Old Masters in the Louvre to find their own voice.

How did Gustave Moreau influence Henri Matisse?

Moreau was a pivotal influence. He recognised Matisse's talent, telling him "You will simplify painting," encouraged him, visited his studio in person, and gave him room to experiment. Matisse said Moreau "disturbed our complacency" and set him "off the roads," a push that was crucial to his development.

What does "cosa mentale" mean in Moreau's teaching?

Cosa mentale is an Italian phrase meaning a thing of the mind. For Moreau it meant that art's true source is the artist's inner world of feeling, imagination, and intellect, not the passive record of external reality. He told his students he believed only in what he felt.

Where did Gustave Moreau teach?

He was a professor and head of an atelier at the Ecole des Beaux-Arts in Paris from 1892 until his death in 1898. He also held informal Sunday teaching sessions for his students at his home and studio on the rue de La Rochefoucauld.

Was Gustave Moreau a good teacher?

He is counted among the most influential and best-loved teachers of his era. His students, Matisse and Rouault among them, praised his paternal, encouraging style and his focus on their individual development, and posthumously called him "The Liberator" for freeing them from rigid academic rules.

If this painter is your match

You believe painting comes from an inner world, not only from what you see. You study the masters not to copy them but to find your own ancestors and your own voice. For you technical skill is not the goal but the tool that lets you reach and carry your imagination.

Borrow this: Go to a museum and find a master whose work speaks to you. Do not just copy it: interpret it freely. Ask what they were doing with colour, with composition, with mood, and use their work as a springboard for what you want to say. Trust what you feel over what you see.
