This map of the Saxon Heptarchy is from Edmund Gibson's edition of Camden's 'Britannia'. Gibson announced that his maps engraved by Robert Morden utilised unpublished surveys where available and the knowledge of local gentlemen who supplied corrections. Morden was an accomplished bookseller and publisher who contributed a great deal to geography and cartography. Morden's maps were very popular. 'Britannia' was first published in 1695, and subsequently in 1722, c.1730, 1753 & 1772. Shirley, R.W. (BI 1650-1750) Morden 12; Skelton no. 117.
