This sketch showing a view in the Roman Campagna dates from one of Gourlier's first trips to Italy. It depicts the site of a mineral spring known as the Acqua Acetosa, near the River Tiber, visible in the distance. Gourlier uses long flowing brush strokes to outline the swelling land, and to trace the trails that run across it. Thick slabs of dark paint describe the rock face.
