Cluster 5: The Living Machine (Anatomy & Engineering)
Leonardo life-system node from research dossier
Content Summary
In Milan, Leonardo conducted systematic neuro-anatomy, seeking the "soul" in the senso comune. Simultaneously, he created the automated Masque of the Planets (1490) and the 60-ton Gran Cavallo equestrian project.
Context Notes
In 1489, he documented the human dental formula (32 teeth) and discovered the maxillary sinus. 2025 FLOW-3D simulations prove his vertical, upside-down casting method for the horse would have worked in 3–4 minutes.
evidence notes
RCIN 919057-919058 (skull sections); Madrid Codex II (foundry notes).
Research Question
Analyze the thermal dynamics of a single-pour 60-ton bronze casting.
Cross-Reference Mapping
Brain geometry research informed the proportions of the Vitruvian Man.
Uncertainty Markers
Skull studies; Maxillary sinus discovery; [Myth]: The Horse was impossible to cast.
