A New Map of the Countu of Essex
Smith's 1602 map, with Overton's 1713 cartouche. For many years the original author of these plates was not known, and hence they were (& occassionally still are) referred to as the "Anonymous" maps.
Roads have been added and the cartouche updated, but otherwise it is essentially unchanged since its 1602 debut.
Displayed scale of 6mls = 63.5mm, ie 2.4 miles/inch; scale actual = 3.2 miles/inch, or 1:200,000.
