One of the most formally inventive works in the collection — a composition that combines two completely different visual systems in one picture field. The upper portion blazes with yellow-gold: multiple fan-shaped bursts of parallel strokes in saturated yellow and orange-gold radiate upward and outward from the top edge, filling the upper third with directed energy — not clouds or flames but pure mark-making, a formal gesture that echoes the flow lines of 514 but in warm color rather than monochrome.
Below this golden zone, the entire lower two-thirds of the composition is organized as a dense field of parallel wavy lines — fine, closely spaced, running horizontally across the surface in varying colors: gray-blue, teal, green, pink, with occasional darker stripes of color. These wave lines cover the lower field completely, creating a surface of immense labor and meditative regularity — hundreds of individual marks, each one following the last in a slightly undulating path.
Emerging from these wave lines, half-submerged: two red-brown turtles. They are unmistakably turtles — rounded shells, visible heads, short legs. They move through the wave field as if swimming, their bodies partly described and partly absorbed into the surrounding lines. The turtles are not placed on top of the composition but within it, as if Sidney drew the wave lines around them or over them, integrating the creatures with the system.
The gold sky above, the wave field below, the turtles swimming through it: a complete and deeply peaceful world. Among the most quietly beautiful works in the entire collection.
