Morant's History of Essex
Bowen created a set of eight regional maps for Morant's book, including this one that shows the Hundreds of Uttlesford, Clavering & Freshwell.
Displayed scale of 4 miles = 77mm, ie about one inch = 1.3 miles (1:84,000). This would make it the largest scale map of Essex (albeit using eight sheets) for Essex up to that date; Chapman & Andre will beat it in 1777.
