Artificial castles and simulated army, 1635.
© Science Museum / Science & Society Picture Library
Engraving of two wooden castles, and at the bottom, a mechanism for simulating an army of 100 men, marching and firing at one specific place. In 1635, gunner and master pyrotechnician John Babington published a book from which this illustration comes, and which describes many effects available at the time, some of which he had devised. This work, 'Pyrotechnia or, A discourse of artificiall fire-works', dealt with geometry, the use of fireworks for military purposes, and firework displays for public entertainment.
