    - Compressed **rib cage** meets tense **thighs**.  
    - Hands stage **mind as muscle**.

    > Thought is not airy here—it is **anatomy under load**.

    ### Versions & Patinas

    - Sizes: **petit**, **moyen**, **monumental**.  
    - Patinas: deep **brown**, olive, **green**—each rewrites **light**.  
    - Foundry marks and casting dates anchor **provenance**.

    | Variant | Height | Typical Setting |

    ### Optics Cheat Sheet

    Legibility (L) under daylight (E) with distance (d):

    $$L propto rac{E}{d^2}$$

    Closer, **glancing angles** reveal **tool marks** and **tendon transitions**.

    ### Where to Stand

    - 3/4 view, slightly **below eye level** → silhouette **tightens**.  
    - Oblique sunlight → **patina gradients** read like **time**.

    See it on the **garden axis**—a thought poised to **spring**.

    ### Context & Background

    - The figure **originated** as part of the **Gates** ensemble (upper register).  
    - Early casts vary in **scale** and **surface chase**—watch for **foundry stamps**.  
    - Public placement shaped its **iconography**: a **thinking body** in civic space.

    ### Deeper Dive: Torque & Thought

    Rodin turns **cognition** into **mechanics**—spine, ribs, and wrists collaborate in a **spiral torque**. Bronze’s **memory** of the tool embeds **time** into surface; your eye reads **process** as **presence**.
