    How this atlas reads maps

    Each essay keeps its own analytical vocabulary. To let them be compared and discovered together, we add a single meta-lens of six canonical dimensions - not imposed on the essays, but excavated from the J.B. Harley critical-cartography spine they already share. It is one interpretive frame among many, with its own silences; the crosswalk below is published in full so you can see exactly what it keeps and what it flattens.

    The six canonical dimensions

    Measure
    Geometric & survey fidelity.
    Witness
    Empirical grounding vs. inherited copy.
    Use
    Navigation, fitness for task, reach.
    Cosmos
    Symbolic & meaning density, naming, craft.
    Power
    Politics, authority, boundaries.
    Silence
    Omission, erasure, what is excluded.

    Caveat: Dacia's Sex Lectiones (ordinatio, litterae, restitutio, correctio, rasura, vacat) is a reading method, not a scoring set - only rasura and vacat feed Silence. Native scales (1–5, 0–8, categorical) are normalized to 0–1 for any cross-essay radar.

    Illustration and evidence

    Two kinds of picture appear here, under opposite rules. The image at the head of an essay or a room is a plate: an illustration made for this project. No plate is a reproduction - nothing historical is scanned or photographed into one - though a plate may perfectly well name real places or arrange invented objects that look like real ones. Plates carry no caption, credit or citation, and are marked decorative so screen readers pass over them.

    Reproductions are the reverse in every respect. A historical object appears only inside an argument, never as a header, and it arrives with its repository, citation and locator, a stated rights basis and a link to the record that granted it. Whether it may be shown at all is settled in the corpus rather than on the page: the rights tables hold a candidate back until its object identity, its resolution and its reuse basis have each been resolved. That is why most of the objects these essays discuss are described here rather than pictured.

    Caveat: a plate may label a real coastline, or allude to a document the essay goes on to cite properly further down the page. Neither is evidence. If a picture is making a claim it is captioned and sourced; if it is not captioned, the words inside it carry no more authority than the lighting does.

    Design tokens

    The shell is built on a shared token layer (palette, humanist typefaces, motion). Legacy essays keep their bespoke interiors; cohesion lives in the chrome, not in flattening the art.
