Gustav Klimt · 1898 · Viennese secession
Portrait of Sonja Knips white dress, red notebook and secessionist style
With Sonja Knips, Klimt leaves the wise worldly portrait to invent a more nervous image: light dress, dark armchair, small red notebook, scattered flowers, psychological emptiness and decorative surface. The painting appears elegant; it is actually a turning point.

The short answer
A square portrait where the white dress and the red notebook take Klimt into modernity
The Portrait of Sonja Knips is an oil on canvas painted by Gustav Klimt in 1898, kept at the Belvedere in Vienna. The painting is often seen as one of Klimt's first great secessionist portraits: it retains the elegance of the aristocratic portrait, but introduces a new tension.
Sonja Knips sits in a dark armchair, more purplish-brown than downright red. Her light dress opens like a foamy, almost floral mass, while a small red notebook held in the hand becomes the sharpest warm accent of the composition.
The power of the painting comes from this setting: whiteness of the dress, dark background, enveloping armchair, bouquet in the foreground, face slightly set back. Sonja is both close and distant, visible and protected, worldly and mysterious.
I · Portrait analysis
The painting hesitates between a social living room and an indoor theater
The pose is seated, but nothing is really stable. The dark armchair envelops Sonja; the light dress expands; the look remains reserved; the red notebook catches the eye like a little ember. Klimt establishes a psychology without anecdote.

White as presence
With Serena Lederer, painted shortly after, we understand better what Sonja Knips inaugurates: the white portrait, elongated, silent and worldly, already almost abstract.

Towards modern portraiture
For Klimt, the female portrait gradually becomes a surface of identity, not just a resemblance.
The square
It gives the portrait an almost decorative status, less narrative than a classic vertical format.
White
The light dress captures the light and transforms Sonja into a fragile, almost suspended apparition.
Red
It is not in the armchair as a simplified title, but in the notebook: a compact, kept, almost secret note.
II · Close-ups of the portrait
See what the whole picture hides at first glance
The painting benefits from being looked at in fragments. The face is restrained, the hands lock the red notebook, the dress becomes an architecture of white, and the dark armchair absorbs the figure instead of simply supporting it.

A look back
The face is not spectacular: Klimt keeps it at bay, as if psychology should stay behind the worldly surface.

The red notebook
This is where the warm color focuses. Red acts as an intimate, almost nervous detail in an image dominated by whites and browns.

A white mass
The dress is not just a garment: it becomes a landscape of folds, reflections and material, almost an abstract painting inside the portrait.

A dark, brown and purplish armchair
The seat functions above all as an absorbent mass: it envelops the model and gives depth, without taking the place of the notebook as a colorful accent.
III · Armchair, notebook, dress
The furniture envelops; the notebook awakens the composition
The armchair is not bright red: it acts more like a dark, brown, purplish, very absorbent background. The real red accent is smaller, but more precise: the notebook that Sonja holds in her hand.
Social power
The armchair evokes comfort, wealth and status, but it also encloses the model.
Chromatic contrast
White, dark brown and discreet red respond to each other: Klimt builds tension by dosage, not by cry.
Psychology
Sonja seems calm in the world, but also isolated by this theater of materials and values.

The little red
Looking closely, the strongest red is not a large piece of furniture: it is this small held, almost hidden object that electrifies the portrait.
IV · Birth of the secessionist style
1898: Klimt presents a new idea of portraiture
The painting is presented in the context of the young Viennese Secession. What changes is not only the style: it is the very conception of the portrait, now open to decorative arts, the surface and the atmosphere.
| Before | In Sonja Knips | After |
|---|---|---|
| Social portrait, readable living room, stable depth. | Dark background, ambiguous space, psychological presence. | Increasingly decorative and iconic portraits. |
| Clothing describes social rank. | The dress becomes luminous and almost abstract mass. | Adèle, Emilie, Fritza: clothing and identity merge. |
| The furniture remains accessory. | The armchair becomes an enveloping mass; the red notebook concentrates the chromatic accent. | The decor becomes mental and ornamental structure. |
Key: Sonja Knips is still a social portrait, but something else: an image where the setting begins to think in place of the anecdote.
V · Who is Sonja Knips?
Model, sponsor, collector: a figure from Vienna 1900
Sonja Knips belongs to the environment that makes Klimt possible: aristocracy, big bourgeoisie, salons, private commissions, collections. She is not content to be represented; it enters the social and cultural network of Viennese modernity.

The Secession
The portrait is born in a Vienna which wants to rethink the relationships between painting, architecture, design and modern life.

Belvedere
The museum today preserves the work, which has become one of the milestones of the transition to modern Klimt.

Klimt-Villa
Klimt's portraits are based on a long relationship between commission, pose, sketches and decor.

Compare Sonja Knips to Klimt's large female portraits
The 1898 portrait prepares a lineage: Serena Lederer, Emilie Flöge, Fritza Riedler, Adèle Bloch-Bauer, Eugenia Primavesi. Each time, clothing and decor become language.

Amalie Zuckerkandl
The late figure shows the material, the background and the psychological presence in a more open image.

Emilie Flöge
The dress becomes almost obvious: clothing, surface, identity, modernity.

Adèle Bloch-Bauer I
The fusion between body, clothing and decor achieves an iconic and golden shape.

Eugenia Primavesi
The figure stands in front of an almost autonomous floral decoration.

The Fan Lady
The feminine presence merges with an imaginary garden of motifs.

Pallas Athena
Another image from 1898 where Klimt experiments with frontality, symbol and precious surface.
VII · See and understand
At Belvedere, Sonja Knips dialogues with all of Klimt
In front of the painting, look first at the face, then at the red notebook, then at the dress and the flowers. Only then return to the dark armchair: this is where we feel how Klimt transforms the portrait into a mental image.

Belvedere
The museum provides the best context for comparing Sonja Knips with the golden portraits and great secessionist works.

Installation and decor
The Klimtian portrait is a slow construction: model, clothing, furniture, flowers, surface.

The climate of 1898
Sonja Knips belongs to the moment Klimt left academia to become the painter of Vienna 1900.
