About Paul Klee | Magic Squares, Bauhaus & a Line for a Walk

Who was Paul Klee?

Paul Klee (1879–1940) was a painter, draughtsman and teacher whose roughly ten thousand works are among the most inventive of the twentieth century. He belonged to no single movement: his pictures touch Expressionism, Cubism and Surrealism, yet look like nothing else. Small in size and full of humour, they mix colour fields, signs, arrows, letters and little figures, and their titles are often part of the poem.

From Bern to the Blue Rider

Klee was born near Bern, Switzerland, into a family of musicians, and played the violin to a professional standard all his life. He chose painting instead, studied in Munich, and for years worked mostly in black and white. In Munich he met Wassily Kandinsky and Franz Marc and exhibited with the Blue Rider (Der Blaue Reiter) circle, sharing their belief that art should express inner life rather than copy appearances.

Tunisia, 1914: “Colour and I are one”

In April 1914 Klee travelled to Tunisia with the painters August Macke and Louis Moilliet. The light of Tunis, Hammamet and Kairouan changed his work. He wrote in his diary: “Colour has taken possession of me… Colour and I are one. I am a painter.” The watercolours from the trip break houses, gardens and domes into transparent patches of colour—the start of the squares that would run through his work.

Magic squares and colour fields

In the 1920s Klee painted many pictures made of nothing but small, slightly irregular rectangles of colour, often called his “magic squares”. Nothing is ruled: the lines wobble, the fields differ in size, and each colour is tuned against its neighbours like notes in a chord. Castle and Sun (1928) turns the same grid into a city of triangles, arches and roofs under a flat red sun.

Taking a line for a walk

Klee's best-known phrase comes from his Pedagogical Sketchbook (1925), which describes an active line “on a walk, moving freely, without goal”. Drawings such as Twittering Machine (1922, Museum of Modern Art, New York) show it: a single thin, trembling line builds machines, birds and faces. In his Creative Confession (1920) he summed up his aim: “Art does not reproduce the visible; rather, it makes visible.”

Teacher at the Bauhaus

From 1921 to 1931 Klee taught at the Bauhaus, first in Weimar and then in Dessau, alongside Kandinsky. His lectures on form, colour, rhythm and movement filled thousands of pages and still shape how design is taught. Faces such as Senecio (1922, Kunstmuseum Basel) reduce a head to a circle, a few planes of orange and two eyes—simple shapes carrying a great deal of character.

Ad Parnassum and the late work

In 1931 Klee moved to the Düsseldorf academy. Two years later the Nazis dismissed him, and he returned to Bern; in 1937 his work was shown in the “Degenerate Art” exhibition. Ad Parnassum (1932, Kunstmuseum Bern) is built from thousands of painted dots over broad colour planes, crowned by a pyramid of lines. Despite a severe illness, his last years were his most productive, with more than a thousand works in 1939 alone.

A digital homage in PictorX

PictorX Paul Klee is a browser photo effect inspired by Klee's magic squares, Castle and Sun, Ad Parnassum, his wandering line and his Tunisian watercolours. It is not a reproduction of any museum painting, not an AI forgery of a Klee, and not a claim of authenticity. The pictures on this page are the artists' own works; Klee's own works are best seen at the Zentrum Paul Klee in Bern and in museums worldwide.

No. It is a digital photo effect inspired by Klee's colour squares and lines. Klee's original works remain unique museum pieces.
