Derde plaat met figuren in de vestingbouw, ca. 1702 1702 - 1703

"Derde Plaat met Figuren in de Vestingbouw," an anonymous etching from 1702-1703, is a technical drawing that illustrates various methods of fortification, depicting different geometric shapes and their applications in defense structures. The detailed line work, arranged in a grid format, is typical of technical illustrations of the period and demonstrates the precise geometric principles employed in 18th-century military architecture. The artwork, currently housed in the Rijksmuseum, provides a glimpse into the practical knowledge and theoretical understanding of fortification during a time of significant military development.
