A new installation of sculptures by Mexican-born artist Bosco Sodi places 14 of the artist’s handmade clay spheres at the Harvard Art Museums and marks the first-ever presentation of art on the museums’ outdoor Broadway terrace. Sodi’s practice explores the earth’s elements, marrying age-old traditions of sculpting clay with a contemporary vision of creating simple universal forms that prompt reflection. Drawing on centuries-old techniques passed through the Zapotec culture, Sodi works with Oaxacan artisans, using local clay to sculpt each sphere, drying it outside for up to eight months, and then firing it in a kiln built upon a beach.
