An early edition of this striking sea chart,which charts one of the most important trade routes of the 15th and 16th Centuries.
The map appeared in a number of clearly distinguishable formats over the years. The present example includes Samuel Thornton's name in the cartouche. The map was revised several times, most notably wih the addition os a new cartouche in the second part of the 18th Century. The present example is a fine early impression and includes the full map title in the cartouche, including the attribution to Samuel Thornton at the Signe of the Plat in the Minories, which was removed in later editions.
Later editions of the chart appeared in The English Pilot, The Third Book., first published in the late 17tth Century and later published by Mount & Page for more than 100 years.
