Moll, of Dutch or German origin, became along with Senex, one of England’s most prominent mapmakers, creating highly distinctive and elegant representations as his 1720 map of America. As did his contemporary, John Senex (map here), Moll relied on De l’Isle’s map for charting the Mississippi accurately. Moll was especially useful for his representation of locations of native tribes, yet, like many English cartographers of his day, adamantly stuck to the idea of California as an island—Senex was the same in this folly.
