FIRST STATE, FIRST ISSUE of Jansson’s map of Pembrokeshire and Caermarthen. EXTREMELY RARE. By the 1630s the publication houses of Willem Blaeu and Henricus Hondius were in a race to produce ever more new maps of the world. Hondius in partnership with Jan Jansson began collecting plates of Britain and in 1636 published an ‘Appendix’ of the Atlas including 17 maps, two of which were general ones. Unfortunately they were not ready in time for the English edition published in 1636 and are only found in the German edition. This marks the beginning of the race between the two houses to produce a separate volume devoted to England and Wales which Blaeu would win in 1645. In 1644 a further 11 maps were issued in a Dutch ‘Appendix’ by Jansson. Examples of maps from these early issues are very rare and highly desirable. The plates are often extensively altered for their ultimate issue in the completed work, the ‘Atlas Novus’ of 1646.

The final finished version of this map would include a new title cartouche in the lower right corner and a series of coats of arms across the top of the map. All so-called pre-issue Jansson county maps are very rare and desirable. Jansson was a very successful publisher who continued the business first founded by the great Gerard Mercator and subsequently taken over by the Hondius family.
