    The atlas · meta-layer

    Every essay, in space and time

    A cross-essay meta-layer: the whole corpus of maps plotted on one interactive map, and every essay charted on one shared timeline (ancient centuries compressed). Historical GIS layers hang from the same spine.

    One timeline, every essay

    Note: the scale is deliberately non-linear — a critical atlas measures time the way its maps measured space, with its own compressions and silences.
