Systole And Diastole

Alfred Jensen's Geometric Abstraction: Systole And Diastole

Created in 1962, "Systole And Diastole" exemplifies Alfred Jensen's distinctive approach to Abstract Expressionism through geometric abstraction. This work reflects Jensen's fascination with systems and patterns, drawing inspiration from scientific principles and philosophical concepts. The title references the cardiac cycle—systole being the contraction phase and diastole the relaxation phase—hinting at the rhythmic relationships between the carefully arranged forms on the canvas.

Jensen's work from this period demonstrates his evolution from gestural abstraction toward a more structured, systematic approach to composition. The painting's precise geometric forms interact with vibrant color fields, creating visual tension that belies its apparent simplicity. This piece represents Jensen's contribution to the Abstract Expressionist movement, offering a counterpoint to the more spontaneous works of his contemporaries.

The Artist's Period and This Work's Significance

Alfred Jensen emerged as a significant figure in the Abstract Expressionist movement during the late 1950s and early 1960s. Unlike many of his peers who focused on gestural brushwork and emotional expression, Jensen developed a unique visual language based on geometric forms and systematic color relationships. His work from this period often incorporated references to scientific theories, mathematical principles, and philosophical ideas, setting him apart within the movement.

"Systole And Diastole" belongs to Jensen's mature period when he had fully developed his distinctive style. The painting demonstrates his interest in creating visual equivalents for complex systems and processes. By titling the work with medical terminology, Jensen invites viewers to consider the parallels between biological rhythms and the formal relationships within the composition.

The Precision of Jensen's Technique

Composition and Structure

The composition of "Systole And Diastole" demonstrates Jensen's meticulous approach to geometric abstraction. He employs a grid-like structure that serves as the foundation for the painting's formal elements. Within this framework, Jensen arranges rectangular forms of varying sizes and proportions, creating a dynamic interplay between positive and negative spaces. The careful balancing of these elements gives the work its sense of rhythmic harmony, reflecting the biological processes suggested by the title.

Color Theory and Application

Jensen's color palette in this work showcases his sophisticated understanding of color theory. He employs a range of hues—from warm reds and oranges to cool blues and greens—arranged according to principles of contrast and complementarity.
