I work as a painter, draughtsman, engineer, scientist, theorist, sculptor and architect, and I keep notebooks that join art and science across anatomy, astronomy, botany, cartography and painting.
The situation, the work, the outcome. Ranked by how much the work proves.
I drew machines the way I drew bodies, producing the first form of the modern technical drawing and a perfected exploded view that shows internal components; my engineering studies fill over 5,000 pages.
In the Mona Lisa I developed sfumato, "Leonardo's smoke": oils blended on the surface so no brushstroke shows, with shadowed corners of mouth and eyes that leave the smile unresolved.
