The present work is part of the Pietre series which Fontana worked on from 1954. He expanded on his perforation theme by adding stones and pieces of coloured glass to the canvas to create a material surface. Simultaneously he intensified his palette to highlight the material nature of the work giving it an aggressive but lyrical quality. The Pietre series was the start of Fontana's exploration of nature and a foretaste of the collage and sculpture series he was to develop from 1957.
