Nice example of John Thornton's sea chart of St. Kitts, Guadalupe and Martinique, which first appeared in the English Pilot, Fourth Book, in about 1706.
Includes a fine map of St. Christophers, now known as St. Kitts, showing the parishes, forts, settlements, and churches, along with two other maps on the same sheet.
John Thornton was one of the most important English mapmakers, from the so-called Thames School of chart makers, during the period when Britain dominated mapmaking. In addition to actual chart-making he also was a publisher. He was appointed Hydrographer to the Hudson Bay Company and the East India Company.
The map would later be re-issued by Samuel Thornton and later Mount & Page.
