John Speed (1552-1629) was the outstanding cartographer of his age. By trade a merchant tailor, but by proclivity a historian, it was the patronage of Sir Fulke Greville, poet and statesman, that allowed him to pursue this interest in earnest.

His 'Theatre of Great Britain' was the first atlas of the British Isles: Speed prepared the maps himself about two years before they were published. The present map is taken from the 1627 English edition published by George Humble, who was granted a privilege to print it for twenty-one years from 1608.

The 'History of Great Britaine' (1611) and its companion atlas volume, the 'Theatre of the Empire of great Britaine' (1612) were published together and "were an immediate success: three new editions and issues of each appeared during Speed's lifetime, and a miniature version was first published about 1619-20. The maps in the 'Theatre' became the basis for subsequent folio atlases until the mid-eighteenth century.
