This map is by arguably the most famous English cartographer, John Speed (1552-1629). First published in the ‘Theatre of the Empire of Great Britain’, 1612. It was the first atlas of the whole British Isles. He was a tailor by trade and had a fascination for history. He used numerous sources for the counties and had the plates engraved by Jodocus Hondius in Amsterdam. This issue is from the 1646 edition published by William Humble. Speed’s maps are noted for being the first to include the boundaries of the hundreds, and for introducing town plans on the maps. Here we find on the left panel Beaumaris, Carnarvan, Harlieg, Cardigan, Penbrok and Carmarthen. The right side bears Denbigh, Flint, Montgomery, Radnor, Brecknok and Cardife. Booth p. 30; Evans (1964) p. 7; Roberts (1994) pp. 34-9; Shirley (2004) T.Spe 1g; Skelton (1970) 48.
