His perfectionism, and an apparent tendency to depression, resulted in a small total output, despite the small size of all his pictures. In all about forty paintings are now generally agreed to be by him (see Kressmann below). He made a few etchings, not very successfully. However, his work was highly regarded by other artists and a few important collectors for its quality. He had a clear and direct influence on other Northern artists who were in Rome such as Paul Bril, Jan Pynas, Leonaert Bramer and Pieter Lastman, later Rembrandt's master, who was probably in Rome by 1605. Rembrandt's first dated work is a "Stoning of St Stephen" which appears to be a response to Elsheimer's painting of the subject, now in Edinburgh. Some works by Italian artists, such as the six pictures from Ovid by Carlo Saraceni now in the Museo di Capodimonte, Naples, also show Elsheimer's clear influence. Rubens, who owned at least four of his works, knew Elsheimer in Rome, and praised him highly in a letter after his death.
