Although this is not in Ertz, the Honig Database has tentatively attributed this painting to the circle of Jan Brueghel the Elder. Landscape looks a lot like early Jan, it would be a work done in Italy. In lower right corner are two classicaly-dressed figures walking in wood: I swear I saw this somewhere as a possibly "Tobias and Angel" identification for subject. True that ruins on left of painting seem rather coarsely painted for Jan; who else would have done something like this?? The figures seem somewhat damaged.
