Dudley's Rare Chart of the Mouth of the Amazon River

"Carte Particolare dell' Rio d'Amazone con la Costa sin al' Fiume Maranhan…", Dudley, Robert (Sir)

This is Dudley's very rare map of the vicinity of the mouth of the Amazon River in Brazil. Every river and creek along the coastline is shown with soundings, hazards and good anchorages carefully recorded. The distinctive calligraphy (alla cancellaresca), fine cartouche, compass rose and sailing ship are the fine work of the engraver, Antonio Francesco Lucini. Second state.

Robert Dudley was the first Englishman to produce a sea atlas, Dell Arcano del Mare (Secrets of the Sea). A skilled mathematician and navigator, Dudley was exiled from England and settled in Florence where his atlas was published. He introduced a totally new style for sea charts in the atlas with only lines of latitude and longitude and no rhumb lines. The charts were meticulously compiled from original sources and were both scientific and accurate for the time. This important atlas was the first sea atlas of the whole world; the first to use Mercator's projection throughout; the earliest to show the prevailing winds, currents and magnetic deviation; and the first to expound the advantages of Great Circle Sailing. In an introductory leaf found in one copy in the British Library, the engraver states that he worked on the plates in seclusion for twelve years in an obscure Tuscan village, using no less than 5,000 pounds of copper for the printing plates. It was only issued in two editions and the maps are rarely seen on the market.

A fine impression on heavy, watermarked paper with wide margins and very light toning along centerfold. A very nice example - nearly an "A." There are bluish shadows that appear adjacent to the centerfold on the image which are caused by our scanner and do not appear on the map.
