Entitled: "The exercise of armes for calivres, muskettes, and pikes taken from 'The principles of the art militarie; practised in the Warres of the United Netherlands'. Represented by figure, the word of command, and demonstration. Composed by Henry Hexham quarter-master to the regiment of the Honourable Coronell Goring. Part 1, 1637." The engravings of pike and musket are derived from: Jacob de Gheyn. A pike is a pole weapon, a very long thrusting spear formerly used extensively by infantry. Unlike many similar weapons, the pike is not intended to be thrown. Pikes were used regularly in European warfare from the early Middle Ages until around 1700, and wielded by foot soldiers deployed in close order. Henry Hexham (1585? - 1650?) was an English military writer.
