Horwitz drew directly on graph paper, layering casein paint with pencil to define each cell. Colors—red, blue, green, yellow—are applied with precision, their placement determined by algorithmic progression rather than expressive choice. The grid’s pre-existing lines structure the composition, while hand-drawn arrows and annotations introduce subtle directives, blurring the line between diagram and artwork.

This piece emerged during a period when Horwitz was refining her systematic drawing practice, following early experiments with performance and film. It was produced in Los Angeles, where she remained based throughout her career. Though not widely exhibited at the time, it became part of a growing archive of works that later gained recognition within conceptual and minimal art circles.

In the late 1960s, artists across the U.S. were exploring systems, logic, and seriality as alternatives to expressive abstraction. Horwitz’s work aligned with this trend but distinguished itself through its focus on time-based sequences and limited numerical frameworks. Her use of graph paper and industrial materials reflected a broader interest in dematerializing the art object while retaining its physical presence.

Horwitz’s systematic drawings, including this one, have influenced later generations concerned with rule-based art, data visualization, and the intersection of mathematics and perception. Her work is now held in major collections and studied for its quiet rigor, offering a quiet counterpoint to more overtly political or emotional movements of her time.
