This is a superb example of this uncommon large scale 4 sheet map. Produced originally on 7 sheets, 4 sheets for the map proper, and 3 sheets covering the Title Page and the Coats of Arms of 693 of the Gentry of the County. Warburton’s survey of the county was based on simple techniques, like Ogilby he used a measuring wheel. He employed others to do much of the routine work whilst his main concern was the enrollment of as many subscribers as possible. Many Roman roads are shown, Hills and Churches are raised, and the distances between market towns are measured and numbered in a circle and placed on the respective road. Each sheet is divided into 2 inch squares and numbered along the top margin “1 to 25” and lettered down the left hand side “A to T”; omitting the letter “J” – a method still in use in many atlases today.

A man of little, or limited education, Warburton still had enough natural ability and skill to produce this famous decorative and highly desirable map of Yorkshire. It is one of only 5 county maps done by him. It was Warburton’s intention to issue a complete and extensive County atlas of England and Wales, however, this project never came to fruition due to financial considerations.
