MILAN (AP) — A major exhibit of works from Joan Miro has opened in Milan, revealing how the Spanish surrealist changed techniques and the materials he worked with throughout his life.

"Joan Miro: The Force of Matter," features more than 100 paintings and sculptures representing Miro's interpretation of a world influenced by the surrealists and poets of the 1920s and 1930s.

Joan Punyet Miro, the artist's grandson, says color, shape and material were the key "pillars" of Miro's art. He said his grandfather understood the magic of color, "the magic of interpretation of dreams, and the magic of surrealistic poetry."

The exhibit, curated by the Joan Miro foundation in Barcelona and including pieces from the Miro family collection, runs through Sept. 11 at the MUDEC, the Museum of Culture in Milan.
