A road map is from Laurie and Whittle’s ‘New Traveller’s Companion’. The firm of Laurie and Whittle relied heavily on the plates of Robert Sayer acquired following his death in 1794. Often thought of as mere publishers Robert Laurie (1755-1836) was a noted craftsman. He was a talented mezzotint engraver who invented a method of mezzotint printing in colour, an achievement that won him an award from the Royal Society of Arts in 1776. In the early 1790s he entered the publishing business with James Whittle (1757-1818) as his partner. The acquisition of Sayer’s stock catapulted them into the major league. In 1806 they published a road book entitled the ‘Laurie and Whittle’s New Traveller’s Companion’ which included road maps. They were compiled by Nathaniel Coltman who working for the Post Office was perfectly placed to produce them. Engraved by J. Bye, E. Jones, B. Smith and W. West they covered territory as far as the Isle of Wight and Scotland. The format was a change from the past which up to now had largely followed the strip map format devised by John Ogilby in 1675. Coltman produces here a clear map which covers larger areas for easier reference. The map is strictly functional concentrating just on roads and distances, the earlier use of nearby features such as churches and hills is omitted. It was a success with a number of editions following and alterations were constantly made to the plates to bring them up-to-date. In 1812 Robert Laurie retired and was replaced in the partnership by his son Richard Holmes Laurie and the firm changed its name to Whittle and Laurie.
