‘The small English county map plates engraved by Pieter van den Keere in about 1605 were used by Willem Blaeu for his edition of Camden’s Britannia in 1617 with the addition of two slightly larger folding maps: those of the British Isles and Yorkshire. The plates then came into the possession of the London publisher George Humble who added further maps and reprinted them under the name of John Speed for the first of a popular series of ‘miniature Speed’ atlases’ (Shirley, of the first Humble edition).
