This map of Middlesex is from the first edition of Edmund Gibson’s issue of William Camden’s ‘Britannia’. It is fascinating to see how much London has expanded over the last 330 years, it now takes up the entire county. Gibson announced that his maps engraved by Robert Morden (fl.1669-1703) who derived this map of the county from that of John Seller c.1673. He also utilised unpublished surveys where available and the knowledge of local gentlemen who supplied corrections.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. His maps were very popular. The ‘Britannia’ was first published in 1695, and subsequently in 1722, c.1730, 1753 & 1772. This is an example from the first edition. Skelton (1970) no. 117.
