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. In 1655 Hungary elected Leopold as its king, in the following years so did Bohemia and Croatia. July of 1658, a year after his father's death, Leopold was elected the Emperor at Frankfurt. This despite the French minister, Cardinal Mazarin's interference. He preferred to make Ferdinand Maria, Elector of Bavaria the Emperor. This is a fine large panorama of the procession of the Emperor.
