“Altarpiece No. 1, Group X” is an abstract artwork created in 1915 by Hilma af Klint. Rendered on paper using tempera, this piece is a notable example of the Abstract Art movement. The artwork measures 185 x 152 cm.
The artwork features a distinct geometric composition predominantly showcasing a large, golden circular form at the top center of the canvas, encircled by alternating green and blue rays. Below this celestial motif is a pyramid structure composed of multiple horizontal, colored sections. These sections transition through a range of hues from red and ochre at the base, moving upwards through shades of blue, and culminating in white near the peak of the pyramid. Each of these horizontal segments is bisected by smaller, oval forms suggesting a meticulous attention to symmetry and balance. The solemn background in black highlights these vivid elements, creating a stark contrast that accentuates the vibrancy of the colors used. The entire composition is evocative of a spiritual or transcendental experience, corresponding well with af Klint’s interests in mysticism and theosophy.
