Gerard Thibault d'Anvers (ca. 1574-1627) was a Dutch fencing master and author of the 1628 rapier manual 'Academie de l'Espee' ('The Academy of the Sword'). His manual is one of the most detailed and elaborate extant sources on rapier combat, painstakingly utilizing geometry and logic to defend his unorthodox style of swordsmanship.
