This is the first printed chart of Boston Harbor. It appeared only in the 1689 and 1698 editions of The English Pilot, The Fourth Book. Sellers publication became the most popular navigational manual for ships sailing to the New World during the 18th century. It was constantly updated with 37 editions appearing between 1689 and 1794.
This rather simple diagram of the harbor was quickly replaced with a chart based on a new and more detailed survey of the harbor and bay. The new chart appeared in various editions of The English Pilot published by Mount and Page from approximately 1707 to 1732.
