Ainslie's large and detailed map of Scotland.

First published in 1789, this large and rare map would become the benchmark map of Scotland, until Aaron Arrowsmith's map of Scotland some 20 years later. The map is on the same scale (approx. 4 inches to 1 mile) as Dorret's map of 1750, however, it surpasses it in terms of clarity and accuracy; and for the first time the Great Glen from Inverness to Fort William is accurately depicted, as are many of the islands that make up the Western Isles.

John Ainslie (1745-1828) was, without doubt, the outstanding Scottish cartographer of his generation, producing a vast range of town plans, estate surveys and county and national maps and charts in a very prolific career. He is best remembered for his nine-sheet map of Scotland and his travelling map of Scotland, however, he also surveyed numerous Scottish counties including the Stewartry of Kirkcudbright in 1796. In 1812, he produced a comprehensive treatise on land surveying based on his practical experience.

The present map is the second edition with the imprint of Thomas Brown.
