A GENERALL CHART for the WEST INDIES According to MR. EDW. WRIGHT'S PROJECTION Commonly called MERCATOR'S CHART, Edward Wright. Richard Mount & Thomas Page, London.
Edward Wright (bptd 1561; d.1615) was an English mathematician and cartographer noted for his book Certaine Errors in Navigation, which for the first time explained the mathematical basis of the Mercator Projection, and set out a reference table giving the linear scale multiplication factor as a function of latitude, calculated for each minute of arc up to a latitude of 75°. This was the essential step needed to make practical both the making and the navigational use of Mercator charts.
