This finely engraved plate presents an intricate grid-based camp layout, rendered with the precision of an architectural floor plan. Numbered and lettered blocks map out formations, quarters, and pathways in a symmetrical, almost modular composition — the kind of graphic design that reads beautifully as a standalone piece independent of its historical subject (a Roman military encampment). Two narrative vignette scenes of Roman soldiers and generals frame the diagram. Engraved and signed "J.V. Vianen del. et fecit" (Jan van Vianen), c.1690–1720.
