Ismael DÃaz honors the art of Diego Rivera by replicating his painting on a ceramic sculpture. The painting features a nude woman with long braids down her back. She is kneeling as she holds a large bouquet of calla lilies in her arms. The sculpted piece is known as metate or metatl, as the Aztec people refer to it. It was designed for grinding maze, seeds and grains by rolling the stone up and down the slightly convex and rugged surface. The metate is still used in many Mexican households.
