The Theatrum Europaeum "was a journal on the history of the German-speaking lands by Matthäus Merian, published between 1633 and 1738 in 21 quarto volumes" (Wiki) and is a great historical source for our epoch of interest, especially Merian's depictions of the TYW battles.

The University of Augsburg has published the whole work:

Thanks Adebar, in the past years i collect many pages of Theatrum Europaeum but with this links it is very simple to research a single battle or commander !
