Introduction
Leonardo da Vinci pursued anatomy not only to serve art but to know what flesh conceals. Dissection and drawing are interventions that turn hidden structure into observable evidence—an early workshop version of active perception.
Craft knowledge and inference
Studio practice—layering, measurement, iteration—mirrors scientific modeling: both seek generative accounts that predict appearances from deeper organization. Renaissance sheets record not only findings but process: where Leonardo hesitated, erased, and re-cut.
Ethics of exposure
Making interiors visible carries obligations: consent of the dead is mediated through social contracts; making model interiors visible in AI carries analogous duties about provenance and harm. Transparency is not always innocence; sometimes it is spectacle.
Art history and science studies
Historians of science read Leonardo’s notebooks as hybrid objects—images arguing with text. That hybridity anticipates modern lab notebooks that interleave plots and prose.
Conclusion
Dissecting the hidden is never only epistemic; it is craft, courage, and restraint. Volume 3’s hidden-state theme gains a tactile ancestor in the table where Leonardo learned to let the body correct his drawings.
