Abstract :
Discusses an unsigned London made sector [London, Science Museum], a mathematical instrument which provides instrumental solutions to trigonometrical problems. The instrument is identified as being made to the design published by Sir Jonas Moore in 1673 with scales specifically intended for use in drawing ground plans for fortifications. It encapsulates the codified design rules of various 17th-c. engineers. One of the fortification scales which adopts general rules of the Count de Pagan, is attributed to Charles II. The use of the sector is explained and the Carolian design parameters compared with others. Consideration of the design work of the King's Engineer, Sir Bernard de Gomme, suggests that his royal master may have influenced that engineer's acceptance of Pagan's rules. Specifically de Gomme's design for Tilbury Fort is seen to follow design ratios probably attributable to Charles II and issued on a medal in 1666. ;
