Compiled by an Englishman but published in Italy, this was the earliest printed sailing chart showing New England. It appeared in Dudleys marine atlas, which was the first such atlas made of charts drawn on the Mercator projection. Many of the charts also identified prevailing winds, currents, soundings, and magnetic declination.
Dudley, son of the Earl of Leicester and brother-in-law to Henry Cavendish the navigator, was exiled from England at a young age for his pretensions to the royal line. He spent most of his adult life in the learned city of Florence.
