Ertz dated this much later than Neumeister does. He called it 1606-11, whereas she says that the landscape looks ore like Jan's style and coloration from around 1600. Query what documentation we have of Jan & Rottenhammer collaborating as late as 1610-11, when Jan was surely working mostly with local artists.
Note that the size of this copper plate differs from Jan's "usual" and that it must have originated in the workshop of Rottenhammer. The copper plate is however a reused one; it seems to have been originally used for an engraving of some sort.
