Nice example of this rare early sea chart of the Eastern Caribbean Islands, from Puerto Rico to Trinidad, Tobago, and the coast of Venezuela.
This is the second state of the chart, which first appeared with the imprint of Jermiah Seller & Charles Price, which has been erased in the second state.
The map is one of the earliest English sea charts to focus on the eastern Caribbean, at a time when the English were becoming increasingly active in the Caribbean, following the taking of Jamaica from Spain in 1655 and the Treaty of Madrid in 1670 between England and Spain, which formalized English control over Jamaica and other territories, followed by the chartering of the Royal African Company in 1672, which facilitated England's entry into the Triangle Trade.
The map was published for inclusion in Seller & Price's English Pilot Book Four, and would be reissued up to 1732, thereafter being replaced by a new copperplate with a different title, A Correct Chart of the Caribbee Islands, published by Mount & Page.
John Thornton was a respected and prominent chartmaker in London in the latter part of the seventeenth century. He was one of the final members of the Thames School of chartmakers and served as the hydrographer to the Hudson's Bay Company and the East India Company. He produced a large variety of printed charts, maps, and atlases in his career, but he was also a renowned manuscript chart maker. Born in London in 1641, he was apprenticed in the Drapers Company to a chartmaker, John Burston. After being made free of the company (1665), he was part of the combine that took over John Seller’ English Pilot in 1677. Thornton was trusted by the naval and navigational establishment of the day; one of his clients was Samuel Pepys, naval administrator and diarist. Thornton died in 1708, leaving his stock to his son, Samuel, who carried on the business.
Samuel, born in ca. 1665, also had apprenticed in the Drapers Company and was made free a year after his father’s death. He continued the business until 1715, when he died. His stock then passed to Richard Mount and Thomas Page.
