Cornelis van Poelenburgh was a Dutch landscape painter and draftsman of the Dutch Golden Age of painting. He was a leading representative of the first generation of Dutch landscape painters who worked in Rome in the early 17th century. In a group of fellow Dutch Bentvueghels he was nicknamed Satyr. Pulenbrüerg was known for his small paintings depicting Italian landscapes with small figures depicting biblical or mythological scenes.
Oswald Achenbach was a German painter associated with the Düsseldorf school of painting. Though little known today, during his lifetime he was counted among the most important landscape painters of Europe. Through his teaching activities, he influenced the Kunstakademie Düsseldorf. His brother, Andreas Achenbach, who was twelve years older, was also among the most important German landscape painters of the 19th century. The two brothers were humorously called "the A and O of Landscapes" (a reference to their initials matching a common German reference to the Alpha and Omega).
