In the motley crowd of people that I have met throughout my life, Sophie Taeuber was the most graceful and the most serene. She lived like a figure in a prayer book, studious in her work and studious in her dreaming. The reality of her dreams never foundered in the reality of days. She was perfectly familiar with both realities. Whether working in the garden, painting, or preparing for a trip, she would devote herself to each task with a cheerful zeal and never rest until she had performed it perfectly. Often I would catch her as she bent over a table, attentively preparing her colors, carefully wiping the brush on the edge of the saucer, diligently applying it to the canvas, piously sketching the lines. Sometimes she would glance up and smile with charming pride. Day and night were full of marvels for her. She always looked forward to the coming of evening and dreams. A dream would continue after she awoke, and at breakfast she would speak about radiant worlds, sonorous forms, marvelous tales in which roses and shadows, huge and blazing sun-umbrellas, happy souls and flights all met in torrents of infinity. Walking with her was unspeakable bliss. She greeted the world in tranquil joy. Every morning she would visit her flowers like friends. She spoke to flowers and stars. She spoke simply to both the tiniest and the largest creatures. She imitated the chewing of crickets by wrinkling up her nose with amused concentration. She took the trouble of carrying away in her closed hands the moths that had strayed around a lamp. I don't know what mysterious intelligence was exchanged between her and the butterflies. They would always come hurrying to her; if she stretched out her arm, they would alight upon it; they settled on her hat, her dress, and rested on her during long walks. Calmly and precisely she would motion to them; and they would obediently fly before or after her. She played with these lovely creatures and fled from them, laughing. The carillon of her laughter was unforgettable. I met Sophie Taeuber in Zurich in 1915. Even then she already knew how to give direct and palpable shape to her inner reality. In those days this kind of art was called "abstract art." Now it is known as "concrete art," for nothing is more concrete than the psychic reality that it expresses. Like music, this art is a tangible inner reality. In the memoirs that the Parisian periodical XXe siècle published, I wrote: "In 1915 Sophie Taeuber and I painted, embroidered, and did collages; all these works were drawn from the simplest forms and were probably the first examples of 'concrete art.' These works are realities, pure and independent, with no meaning or cerebral intention. We rejected all mimesis and description, giving free rein to the elementary and the spontaneous." In 1915 Sophie Taeuber was already dividing the surface of a water color into squares and rectangles which she juxtaposed horizontally and perpendicularly. She constructed her painting like a work of masonry. The colors are luminous, going from rawest yellow to deep red or blue. In certain compositions she introduces on different levels squat and massive figures anticipating those she subsequently fashioned in wood. These figures could blosson into plants, dolls, vases, which in turn became faces reflecting the dread of solitude and death. But the vigor of youth, in its richness and brightness, disperses these shadows. The water colors of the following period (circa 1920) are a multicolored fabric of innumerable square and rectangular spots. Light and shadow flourish, and no noisy clash or contrast disturbs the harmony. Sophie Taeuber was overwhelmed by the feeling of decrepitude, fragility, and complete inadequacy generated by earthly things. She rejected the vanity of artistic fakery and saw perfection in humility. Around 1930 she adopted a mode of composition in squares and rectangles on a black or white unicolored background. Sometimes she would introduce triangles or circles. She would often connect these figures with straight lines and animate them against their white or black depths with a rising or falling movement or an oscillation, or else keep them motionless. Her palette knew hardly any colors but blue, red, yellow and green. She conceived her works in larger dimensions and did them in oils. Around 1933 she eliminated straight lines, triangles, rectangles, squares, and used only circles. The composition always proceeds from a very strict basic arrangement that, after protracted work, always frees itself in two or three dots from which the total power of the picture radiates. They give it its tension and fill it with life and soul. Several works in that period sometimes contain four or five different compositions interwoven. These paintings are likewise composed on a black or white monochrome background. She was painting the chessboard of night. White, red, and green spheres serve as pawns for the night. The night plays with the visible and the invisible. The invisible beats the visible. From 1936 to 1938 she did a series of wood reliefs. Certain of these reliefs contain simple groupings of geometric forms, appliquéd, cut out, or jutting. These reliefs are painted white, black, red, and blue. The relief entitled Sea-shell Armor-- vibrant white forms on a rectangular background-- attains the perfection of beauty. It is with works of this sort that the word beauty assumes its living sense. The last of these reliefs was composed at the time when Sophie Taeuber was drawing a series of vases, leaves, and metamorphosed sea shells to illustrate my book of poems Sea Shells and Umbrellas (Muscheln und Schirme): this last relief is so unusually perfect, its inner brightness is so great, that I can compare its beauty to nothing less than that of a Greek amphora. Most of the reliefs of that same period evolve from a circular background. Earth and sky are intermingled like waves. Dark-green leaves, deep-blue skies. These works have the solemnity of a wing, the splendor of a glittering jewel. In the years 1932, 1938, and 1939, Sophie Taeuber did four large compositions in oil, in which she went back to the system of geometric division of surface that she had used for her water colors in 1916. She divides the surface into four, six or eight rectangular or square planes of equal size, sometime uniting two or more of them in a single flat level organized into smaller ones. Depths take shape and give the whole a plane spatial reality. These surfaces no longer detach themselves from the background as in the paintings done in 1933: now they are two-dimensional spaces in which plane depths open up; surfaces settle on other surfaces, lean on them, seem to advance toward the onlooker, sink away, float along lines like flags on their poles. These are two-dimensional spaces in which lines cut through surfaces, limit the areas of light and dark, and share the image with one another. Sophie Taeuber called those paintings Space Paintings. These plane and spatial realities are created merely by the play of colors and surfaces without the help of perspective or illusion of volume. The image always remains flat, and never transgresses the law dictated by the very nature of objects: the two-dimensionality of any picture. Sophie Taeuber spent the last two years of her life with me in Grasse, a town in Southern France. She really loved that area: it was her earthly paradise. Whenever we went for a stroll, she was radiant with happiness. She kept urging me on to more and more walks. Her eyes were always fastened to the silvery-green olive groves, the meditative silhouettes of the shepherds amid their flocks, the villages jutting up on the mountains, the flittering, dazzling shield of the ocean. We lived between a well, a graveyard, an echo, and a bell. A palm tree and some olive trees grew in our garden. Whenever the palm fronds began to rustle, there was rain. The olive trees were constantly animated by an almost imperceptible thrill: each day was brighter and happier than the preceding one, and Sophie equaled them all. Her inner clarity struck everyone who met her. She blossomed like a flower about to droop. The bright inwardness of her being brought protection and comfort to anyone in suffering. From her purity she drew the courage and confidence to endure the immense misfortune of France. Her paintings were filled with glorious brightness. From the depths of the most intense suffering, blossoming spheres shoot forth. Depths and heights and rays rise and drop in a vast colored round. Lost and impassioned, she drew lines, long curves, spirals, circles, roads that twist through dream and reality. She painted her final singing circles. In the turret where she had her room, she worked ardently. Her fine approving profile lowered and rose before the distant sea. The day before we left Grasse, she meticulously put her tools in order and carefully stood her paintings against the wall to let them dry. She was as content as one is after a lovely day. She was always ready to receive darkness or light calmly. She was serene, bright, truthful, precise, honest, incorruptible. She opened life to skies of brightness.
