Matthaus Merian began publishing the 'Theatrum Europaeum' in 1633, it was not finished until 1738 by which time 21 volumes had been issued including some 20,000 pages of text, 720 maps, plans, views and other engravings and nearly 700 portraits. This is a map of Brandenburg in Germany, wonderfully engraved by the talented Matthaus Merian. Berlin is situated just below the middle of the map.
