This is an exhibition held at the Mount Tabor Ecumenical Center for Art and Spirituality in Barga (Lucca) in the days of the international conference "The arts and ecumenism" and subsequently at Cape Code, Boston MA, (USA). In this third collaboration, Filippo Rossi and Susan Kanaga explore images of light within the context of abstract sacred art. Rossi, an Italian Catholic, and Kanaga, an American Protestant, approach light, a major and complex symbol, through their religious traditions. Polistampa catalog, Florence.
