A triangulation diagram appears on the reverse of this drawing. This enabled draughtsmen to plot the exact location of topographical features. Mileage is indicated on major communication routes, accompanied by abbreviations of the town names from which distance has been measured. For example, the abbreviation 'MS L''2' indicates two miles from Llangollen. Archaeological sites are named in gothic script. A triangulation grid is faintly visible in the left hand portion of the drawing, and pencil lines radiate from trigonometrical stations, marked by dots within triangles.

DENBIGH AC FLINT Sheet 37
This map of Denbigh and Flint is from the 1583 edition of the Saxton atlas of England and Wales.This atlas was first published as a whole in 1579. It consists of 35 coloured maps depicting the counties of England and Wales. The atlas is of great significance to British cartography as it set a standard of cartographic representation in Britain and the maps remained the basis for English county mapping, with few exceptions, until after 1750. During the reign of Elizabeth I map use became more common, with many government matters referring to increasingly accurate maps with consistent scales and symbols, made possible by advances in surveying techniques. Illustrating the increasing used of maps in government matters, Lord Burghley, Elizabeth I’s Secretary of State, who had been determined to have England and Wales mapped in detail from the 1550s, selected the cartographer Christopher Saxton to produce a detailed and consistent survey of the country. The financier of the project was Thomas Seckford Master of Requests at the Court of Elizabeth I, whose arms appear, along with the royal crest, on each map.
