De militia equestri antiqua et noua ad regem Philippum IV libri quinque
De militia equestri, a 1630 Latin treatise on cavalry tactics by Herman Hugo, printed at Antwerp by the Plantin press for King Philip IV of Spain, with plates after Cornelis Galle and Jacques Callot. The pictures are engraved formations: rows of mounted horsemen and pike or musket blocks shown in plan, with the battle order and manoeuvres drawn as small figures on open ground, useful for designers seeking early-seventeenth-century military order, crisp diagrammatic layouts and stylised tactical arrangements.
