John Latham Knapp is a painter and sculptor interested in the cross-cultural referencing of form and symbol. Sculptural concerns are often reflected in painting and vice versa. Found objects and arte povera materials are important to the work. His artwork reflects a continuity of thought and evolving themes that spans more than 30 years.

Recent themes in painting and sculpture use archetypal form and visual imagery as yantra. Two-dimensional work includes paintings on luan often incorporating copper or steel, photography, works on paper and collage. Sculpture is made of steel and wood, cast cement or natural stone, colored and juxtaposed with steel or wood.
