His work marks a transition between late Baroque drama and the softer sensibilities of the Rococo. Trevisani is known for his use of soft light and emotional clarity. In works like Dead Christ Supported by Angels, he avoids harsh contrasts in favour of delicate transitions. His preparatory drawings, such as his red chalk studies of flute players or kneeling figures, reveal a meticulous focus on anatomy and grace. He often used a cool palette of blues and silvery greys to create a sense of quietude.

Modern collectors value Trevisani for his ability to balance grand scale with intimate emotion. His paintings avoid overwhelming a room with aggressive action, offering a calm and atmospheric presence instead. The sketches and x-radiographs in our collection provide a look at his technical process. These works suit interiors that require a touch of historical weight without the visual clutter of earlier Baroque styles. His art provides a window into the refined aesthetic of eighteenth-century Rome.
