Madí artists were among the first to make shaped canvases that echoed the composition, rather than allow the standard rectangle frame to determine its form. Martín Blaszko’s untitled painting is a prime example. The shape of the polygonal frame follows the dynamic rhythm of crisscrossing diagonals, contrasting colors, and playful patterns. Using the classical system of proportion called the Golden Section, Blaszko delighted in balancing opposing forces and creating a sense of visual harmony.
