The lozenge compositions
Along with the rectangular canvases, throughout the 1920’s Mondrian worked also on a series of compositions developed on a lozenge format.
The choice of this format gives greater breadth to the composition. It makes it possible to use lines of various lengths.
New relations of tension are established between the orthogonal planes and the diagonal sides of the painting.
The four corners of the lozenge generate a centrifugal energy and seem to expand the plane of the canvas along its two median axes.
More dynamic
The lozenge therefore already seems in itself a way to make the equivalence of opposites, i.e. the square, more dynamic.
On observing the four lozenges we note how a closed area nearing the proportions of a square (first lozenge) opens up (second and third) while in the fourth one a closed square re-appears which consists of lines which assume variable thickness. On the one hand an open square area extends with the lines toward a virtually infinite space (the finite opens up to the infinite; the one opens up to the many) and on the other hand a renewed closed square is made of a relative multiplicity through lines varying in thickness. In both cases, the one interacts with the many. Once again, Mondrian seeks in these works to open and expand the square while maintaining its visibility at the same time.
A synthesis of all the lozenges
We shall now examine Lozenge with Yellow Lines which constitute a synthesis of all previous compositions of this type.
The square in this composition has the same proportions as the canvas. The four lines show a progressive increase in thickness as we move clockwise from the vertical on the right. The increase in the thickness of the lines can be seen as the vertical incorporating a slight horizontal expansion or conversely as the horizontal growing thicker in response to barely perceptible vertical pressure. For a fraction of a second, the space of the lines is simultaneously vertical and horizontal, i.e. a synthesis of the opposite directions. From this point of view the lines seem to transform into embryonic planes.
We actually talk about a square that we do not really see in full since the lines never meet inside the canvas. In point of fact each line could well continue on its own towards infinite space without being really concerned to merge with the opposite lines as to give birth to a square. Our mind translates infinite space (each uninterrupted line) into a presumed finite space (a square form); four separate and different elements (different because of their variable thickness) hint at a probable square unit which is, however, beyond our field of vision. Mystical thought invites us to consider the variety present in nature as an intrinsic unity. A unity which is not visible except by individual separate parts.
The more important innovation is obviously the fact that, for the first time, the lines are no longer black but yellow. The field is uniformly white and the yellow shape almost appears to be born out of the white rather than in opposition to it, as in the case of the black.

Yellow is an intermediate value between black and white, sufficiently dark to be differentiated from white but, at the same time, not so radically opposite as black. The opposite values now seem communicate and achieve unitary expression in terms both of form and of color, with horizontal and vertical simultaneously present for an instant in every line and the synthesis of black and white in an intermediate color, which yellow appears to constitute in this case. On observing this square and contemplating the differing thickness of the lines, we are faced with a unity undergoing transformation from one side to the other; a synthesis that already appears comparatively manifold in itself. We perceive a unity that tends to become rather than to be. It endures but changes at the same time; a square that is open, dynamic, asymmetric, and entirely expressed by color.
One and the same thing
This composition goes to the heart of the problem: to show the manifold in unitary form; to open up unity, i.e. the postulate of consciousness, to the changing aspect of the natural universe and existence in time but without losing sight of it. Once again we recall the fundamental issue: The one and the many appear as antithetical realities in the human dimension; in actual fact, they are one and the same “thing”.
The dialectic between unity and multiplicity continued throughout the 1920s and early 1930s. The single white square field (1920) took on color, underwent duplication while opening up on one or two sides (1930). A closed square developed out of the dynamic continuity of the lines around 1931: the square is sometimes more horizontal, sometimes more vertical; sometimes larger, sometimes smaller; sometimes blue, sometimes yellow. The single square of 1920 gradually gave way to a variety of probable square forms. Unity and multiplicity tended to interpenetrate.
In actual fact, the square opened up and interpenetrated with the variety of forms and colors in the rectangular canvases while seeking in the lozenge compositions to absorb that variety with no extensive change to itself. In the first case, the square opens up in the direction of multiplicity; in the second, the square absorbs multiplicity while remaining substantially one:
In this phase Mondrian is like a composer who gradually reduces the orchestra to a solo instrument, an almost imperceptible sound that can still be varied in an effort to express the whole. In a white field crossed by four black lines, the thickness of a line can also serve in a space moving toward ever-greater synthesis to calibrate the weights and influence the overall economy of the composition.
These lozenge compositions constitute the moment of greatest correspondence between the one and the many.
With the canvases of the late 1920’s and above all this lozenge of 1933, the artist appears to have given material expression to an idea that had guided him, canvas after canvas, for roughly twenty years of work, namely to express the multiple in unitary form and endow it with the stability required by consciousness without, however, causing it to atrophy in overly rigid and constant geometric forms. The artist felt for a moment that he had achieved his objective with a square undergoing transformation while remaining relatively stable.
Nonetheless, if we compare Lozenge with Yellow Lines with the previous works and in particular with those produced up to 1920:
it appears immediately obvious that by 1933 the multiple aspect had been considerably reduced almost to the point of elimination. Around 1930 Mondrian painted in black and white or with one or two colors inside predominantly white fields. In the span of a decade, the manifold space (1912 – 1919) appears to have been completely absorbed by the square, which was used during the 1920’s and early 1930’s in an attempt to reformulate in conceptual synthesis a space that is in reality far more structured and complex. The square we see in Lozenge with Yellow Lines is a symbolic representation that does not suggest the variety of the real world. In 1933 the space of external reality had undergone marked internalization in the far more condensed forms of thought; the physical seemed to be expressed in excessively mental terms.
The painter was soon to realize that his canvases did not convey a sense of the variety perceived by the eye in nature or urban space, the rich and multiform aspect of color previously captured with his dunes and trees, his Cubist works, and his checkerboard compositions. While Lozenge with Yellow Lines can therefore be regarded as a point of arrival, at the same time, as in other moments of Mondrian’s artistic development, the work also represents a new point of departure.
As Michel Seuphor puts it in his beautiful biography of Mondrian: “Sometimes he thinks he has found it. So he stops, observes the work, and says: It’s done. But the clock of his life keeps on ticking and is already driving him forward. He soon realizes that nothing is done and everything has to start all over again.”
