A mask made of letters
A pale, masklike face fills the centre of Paul Klee’s Death and Fire. Its dark features can also be read as the letters T–O–D, spelling Tod, the German word for death. Around it, heavy black lines cross a field of warm orange and yellow. A bright disk at left and a smaller angular form at right invite further recognition without becoming a settled scene. Klee gave this 1940 painting a title that contains both death and fire. The face supplies a visible link to the first word; the second remains open to several visual associations.[1][2]
The painting was made in the year Klee died. That proximity is important, but it does not tell us the work’s exact day of completion or turn each mark into a medical symptom. Its physical construction, letters, colours and later philosophical reception each have their own evidence. Looking at them separately makes the picture more complex than a last message decoded once and for all.[1][3]

Title, numbers, size and collection
The German title is Tod und Feuer. The artist entered it in his annual work list as 1940,332. A later catalogue raisonné assigns continuous number 9351. These are different cataloguing systems: the first places it in Klee’s 1940 sequence, while the second identifies it across his whole oeuvre. A 2008 Staatliche Museen zu Berlin exhibition checklist lists the work at the Zentrum Paul Klee in Bern and gives its size as 46.7 × 44.6 cm. A 2025 Zentrum Paul Klee guide treats it as part of the museum’s collection. The museum’s image agency also associates it with identifier ZPK000020, though that image-record code should not be mistaken for a verified current accession number.[1][2][4]
The 2008 checklist describes the medium in German as “Öl- und Kleisterfarbe auf Jute auf zweiter kleistergrundierter Jute auf Keilrahmen”: oil and coloured paste paint on jute mounted on a second, paste-primed jute, on a stretcher. Published English versions vary among “paste paint,” “coloured paste” and “glue paint” for Kleisterfarbe. None of these short translations should erase the two jute layers. A 2003 Fondation Beyeler exhibition caption and a dated collection presentation also record original double frame strips. Beyeler rounds the dimensions to 46 × 44 cm; the Berlin checklist’s more precise figure is the useful object caption, with the historical variant retained in the research record.[1][5]
This layered textile support matters to how the image meets the eye. Jute has a pronounced weave compared with a smooth primed canvas. The coloured paste and oil meet the fibres and prepared layer differently from a thin line on paper. Broad dark marks sit among rougher areas of colour, while the pale face remains visually forceful. The available catalogues document the support, but a museum conservation file would be needed to describe its exact ground chemistry, the order of every paint application or subsequent treatment. The older phrase “oil on distemper on jute” is too compressed to do that work.[1][2]
Seeing a face, reading a word
The central pale form can appear as a head, mask or skull. Dark marks supply features, yet those same marks can be followed as T, O and an inverted D. The German word Tod emerges from a face that seems to stare back. The Zentrum Paul Klee’s guide identifies this overlap explicitly. Art historian Claude Cernuschi also examines it in his study of Klee and language, describing how the viewer moves between recognising a face and reading a familiar written word. Neither task cancels the other. The ambiguity is the pictorial event, not a puzzle whose solution makes the face disappear.[2][6]
The letters are not placed below the portrait like a caption. They make up the portrait’s own features. Once the word has been seen, it is difficult to return to a wholly innocent face; once the face returns, the letters cease to behave like ordinary writing on a page. Cernuschi situates this switching within a broader discussion of Klee’s use of linguistic and pictorial signs. His chapter compares visual perception with later cognitive research, but that modern comparison should not be turned into a claim that Klee knew brain-scanning science or intended a neurological experiment.[6]
One can try to find a second spelling of TOD beyond the face. Ōhashi’s 1988 study proposes another arrangement in the figure and nearby circle, treating the word as present in both facial features and bodily gesture. This is a specific scholarly interpretation, but the ZPK and Cernuschi face reading has firmer support in the object-focused sources checked. Ōhashi does not supply a statement by Klee confirming that the additional shapes were intended as a second complete word. A reader can test his proposal without being told that every proposed letter is settled. A small website image is especially poor evidence for the exact orientation of a faint or ambiguous mark.[2][6][8]
The right-hand form may suggest a person, a child or a sign assembled from a few strokes. The disk at left may evoke flame, sun or a source of light because of its yellow colour and the painting’s title. None of these identifications is fixed by an artist statement available for this work. The angular form, disk and central face share the same warm field; their relation creates tension without providing a continuous story. The title Death and Fire names themes, not every object or action pictured.[2]
A late work with a particular surface
Klee died on 29 June 1940. ZPK calls Tod und Feuer one of his last paintings, finished shortly before his death. The annual number 332 establishes an entry in his 1940 sequence, not a day or month. Nor does “one of his last” mean “the final work.” Other 1940 works, including an untitled still life, have their own claims in accounts of his final production. The exact chronology and any studio circumstances should be checked against the artist’s handwritten register and correspondence before a dramatic final-scene narrative is attached to this painting.[1][2]
The mask and letters are stark, but the composition is not simply drained of life. Orange, red-brown and yellow areas vary around the pale centre. Heavy black signs create a loose framework rather than an even outline around every form. Near the lower edge, a lighter strip interrupts the warm field. These relations ask to be looked at as colour and construction, not only as an illustration of the title. The jute’s weave and paste paint give the marks a physical resistance absent from a smooth digital reproduction.[1]
It is tempting to explain the breadth of the strokes as the involuntary result of illness. Klee was seriously ill in the later 1930s, and his health belongs in a biography of the period. Yet the familiar diagnosis of scleroderma was made retrospectively after his death. Researcher Walther Fuchs has cautioned against making the surviving art serve as a clinical chart. ZPK’s own public guide sometimes speaks of late roughness as caused by the illness, but the catalogued material and visual decisions cannot be reduced to that single cause. A broad painted line is still a chosen part of an artwork. Calling the forms “simplistic” confuses economy of form with artistic decline.[2][3]
The ZPK guide suggests the central death mask may be a self-portrait. That is a curatorial possibility, not an identified likeness. The image belongs to an artist who could join human features, signs and painterly gestures in one form. Its 1940 date and mortality word make an autobiographical association compelling, while the absence of a recorded declaration by Klee leaves the exact subject open. The painting can engage death without becoming a literal portrait of its maker awaiting a known date.[2][6]
How writers have used the painting
The work’s afterlife is unusually rich. It has appeared on book covers and in discussions of late style, language and philosophy. The Zentrum Paul Klee’s 2025 Cover Star Klee guide is principally about those later uses. Its German, English and French editions are translations of one curatorial account. They show that the image remains powerful in different reading cultures; they are not three independent pieces of evidence for Klee’s 1940 intention.[2]
The Brazilian scholar Wilcon Pereira, writing in Portuguese in 1974, discussed the painted TOD as part of Klee’s joining of writing and figures. His account is useful as evidence of how critics read Klee’s signs after the artist’s death. It also makes more sweeping claims about the artist’s final years that are not established by the object records or medical evidence used here. The chronology of Pereira’s printed article must not be confused with its later date of online publication.[7]
Japanese philosopher Ryōsuke Ōhashi devoted a 1988 article to Tod und Feuer and Heidegger. He begins with Klee’s writings on line, light and colour, then argues that the painting’s thick dark marks exceed a simple line drawing: they also carry darkness and colour. He reads the red field and black bars as opposing forces, leaving open whether the red can spread or the black can contain it. That attention to an unresolved relation is more useful as a way to look at the painting than as a code that fixes the identity of every shape.[8]
Ōhashi then proposes a more ambitious iconology. The pale face and neighbouring figure become, in his account, overlapping images of a dead person and an angel of death; their conflict opens onto a threat to human existence and to nature. He links this reading to other late Klee works and to the historical fears of Nazism, war and modern technology. These are connections made by a philosopher in 1988, not recorded explanations from Klee in 1940. The article’s later pages compare Death and Fire with Klee’s Saint from a Window: Ōhashi sees danger in the first and a still tentative prospect of rescue in the second. Heidegger named the two pictures together, but the detailed pairing of their colours and symbols is Ōhashi’s, not Heidegger’s own published analysis.[8][9]
In the preface to his 1962 lecture Zeit und Sein, Heidegger imagines the audience encountering two original Klee works from the year of the artist’s death: Heilige aus einem Fenster and Tod und Feuer. He says one would linger before them and relinquish a demand for immediate understanding. He then uses that comparison to prepare listeners for difficult philosophical thought. This is a direct, specific mention of the painting in the primary German text. It is not an analysis of the central face, the letters, the fire or Klee’s state of mind. Heidegger calls the work “Tempera auf Rupfen” in passing, an abbreviated historical description that differs from the later Berlin checklist’s fuller technical wording; the philosophical preface is not the preferred conservation record.[1][9]
The ZPK guide speculates that Heidegger may have seen the picture in a Bern exhibition in 1956 and that it may have appealed to ideas associated with his thought. Those claims remain possibilities until checked against a dated display list and his own notes. His verified 1962 mention is enough to document reception without inventing a conversation between philosopher and painting in 1940. Klee died more than two decades before the lecture. Philosophical associations can enrich a later reading, but they belong to that later moment.[2][9]
Looking again
First look at the pale centre without trying to spell anything. Then search for T, O and the reversed D. Notice which marks have to change jobs to become letters. Move outward to the yellow disk and the smaller dark form, and ask what their placement makes possible without assigning them a fixed role. Finally attend to the support: where does a dark stroke cross rough colour, and where does the light ground show through? Even a limited reproduction can begin this sequence, although the original surface would show more.[1][2][6]
Death and Fire is securely a 1940 work, numbered 1940,332 by Klee, with a two-layer jute support recorded in the Berlin checklist and held at the Zentrum Paul Klee. The word-image in the face is well supported. The painting’s exact personal meaning, a second complete spelling of TOD, and a diagnosis of its style from illness are not established in the same way. Its later readers, from Pereira to Ōhashi and Heidegger, show how a small painted face can provoke sustained thought. Their responses are part of the work’s history, while the mask, letters, warm field and resistant surface remain there for each viewer to inspect anew.[1][2][6][7][8][9]

Discussion
The pale face can be seen as a mask and read as the German word for death.
The research separates the painted object, Klee’s late circumstances and later philosophical readings.
