Extremely rare British chart of the entrance to the Río de la Plata, published by William Faden in London in 1817, based on surveys made by John Warner in 1810-1814.
The chart covers from Sierra de Buena Vista mountain at the far northeast, to Buenos Aires at the far west. There are numerous sea tracks across the entrance to the Rio de la Plata and out into the Atlantic. As these were surveying expeditions, they also include hundreds of soundings along their courses.
A nice engraved view of Buenos Aires is included at the bottom left. It is titled "View of Buenos Ayres from the Nereus's Anchorage, Outer Road." Numbering corresponds to an 18-item key in the map above the view.
The chart includes an inset "The Roads of Buenos Ayres; Surveyed by John Warner, 1814."
OCLC records only one other example of this chart, at the British Library.
We acquired this map in October 2020 from the descendants of James Sever, Captain of the USS Congress, one of the famed first six frigates of the U.S. Navy. Captain Sever was born in 1761, attended Harvard, and upon graduation received an ensign's commission in the 7th Massachusetts Regiment (February 1, 1781) during the Revolutionary War. Sever later transferred to the 4th Massachusetts Regiment and remained in the Continental Army until June 20, 1784. Sever was from a successful Massachusetts merchant family, and that background along with his military experience was enough for him to be named the superintendent of the USS Congress during its construction in 1795. In 1798, he became one of the first six post captains of the U.S. Navy. Sever served in the first foreign action of the U.S. Navy, when the Congress was involved in privateer hunting in the Caribbean and the U.S. intervention in the Haitian War of Knives. Sever had a relatively short career in the Navy and was dismissed during Jefferson's purge of the officer corps in 1801.
William Faden (1749-1836) was the most prominent London mapmaker and publisher of the late-eighteenth and early-nineteenth centuries. His father, William Mackfaden, was a printer who dropped the first part of his last name due to the Jacobite rising of 1745.
Apprenticed to an engraver in the Clothworkers' Company, he was made free of the Company in August of 1771. He entered into a partnership with the family of Thomas Jeffreys, a prolific and well-respected mapmaker who had recently died in 1771. This partnership lasted until 1776.
Also in 1776, Faden joined the Society of Civil Engineers, which later changed its name to the Smeatonian Society of Civil Engineers. The Smeatonians operated as an elite, yet practical, dining club and his membership led Faden to several engineering publications, including canal plans and plans of other new engineering projects.
Faden's star rose during the American Revolution, when he produced popular maps and atlases focused on the American colonies and the battles that raged within them. In 1783, just as the war ended, Faden inherited his father's estate, allowing him to fully control his business and expand it; in the same year he gained the title "Geographer in Ordinary to his Majesty."
Faden also commanded a large stock of British county maps, which made him attractive as a partner to the Ordnance Survey; he published the first Ordnance map in 1801, a map of Kent. The Admiralty also admired his work and acquired some of his plates which were re-issued as official naval charts.
Faden was renowned for his ingenuity as well as his business acumen. In 1796 he was awarded a gold medal by the Society of Arts. With his brother-in-law, the astronomer and painter John Russell, he created the first extant lunar globe.
After retiring in 1823 the lucrative business passed to James Wyld, a former apprentice. He died in Shepperton in 1826, leaving a large estate.
