Framed print of a Musketeer by Dutch artist Jacob de Gheyn II, from his influential military manual, The Exercise of Arms (1608) depicting a musketeer after firing his weapon, with a large plumed hat and a bandolier. The manual was commissioned to provide clear, systematic procedures for training soldiers in the Dutch army with 117 engravings illustrating the use of the musket, small shot, and pike. De Gheyn's detailed engravings are considered valuable for identifying 17th-century military artifacts and understanding the period's military practices.
