ファイル:Senex A map of Louisiana and of the River Mississipi 1721 UTA.jpg

English: For this map, English scientific publisher, bookseller, mapmaker, mapseller, instrument-seller, globemaker, engraver and surveyor John Senex (1678-1740) copied and translated Guillaume Delisle's 1718 Carte de la Louisiane with no credit to the French cartographer. For example, the inscription along the Texas coast in Delisle's map "Indiens errans et Antropophages" became "Wandering Indians & Man-eaters" in Senex's map. Senex's cartouche was different, though, and contains a dedication to William Law, probably a relative of John Law (1671-1729) and possibly his brother. John Law bore much of the blame for the financial panic known as the "Mississippi Bubble" and these maps all appeared around the time of the crisis. Like his brother, William Law the younger (1675-1752) was involved in the administration of both the Banque Generale and the Louisiana Company and was reportedly later imprisoned for fifteen months in the Bastille for corruption.
