from Lutheranism to Catholicism, as Elsheimer did later. Both Faber and Bril knew Rubens, who was in Rome in 1601, and who became another friend, later reproaching Elsheimer for not producing more work. He knew David Teniers the Elder, recently Rubens' pupil, and there is evidence that they lodged together. In 1604 Karel van Mander, a Dutchman recently returned from Rome, published his Schilder-Boeck which praised Elsheimer's work, and described him as slow-working and making few drawings. He also spent much time in churches, studying the works of the masters. Other writers mention his exceptional visual memory, his melancholy and his kind-heartedness. In a letter after his death, Rubens wrote: "he had no equal in small figures, landscapes, and in many other subjects. ...one could have expected things from him that one has never seen before and never will see." In 1606, Elsheimer married Carola Antonia Stuarda da Francoforte (i.e. Stuart of Frankfurt- she was of Scottish ancestry and a fellow Frankfurter), and in 1609 they had a son. The son was not mentioned in a census a year later, possibly (Klessman says optimistically) because he had been put out to a wet-nurse. She was the recent widow of the artist Nicolas de Breul (born in Verdun) and after Elsheimer's death remarried an Italian artist, Ascanio Quercia, within a year of his death. Elsheimer converted to Catholicism by 1608 (possibly 1606). He was admitted to the Accademia di San Luca, the Roman painters' Guild, in 1606, giving them a self-portrait (his only portrait, and only painting on canvas) now in the Uffizi. In spite of his fame and talents, he appears to have both lived and died in difficult financial circumstances. Elsheimer's painting of Tobias and the Angel (1602–1603) (the "small" Tobias - now at Frankfurt) was especially well received because of its new conception of landscape. This picture was engraved by Count Hendrick Goudt and as a result was published across Europe. However, his association with Goudt, who lodged and trained with him for several years, was difficult. Elsheimer seems to have borrowed money from Goudt, which according to one account resulted in his brief incarceration in Debtor's prison. After Elsheimer's early death in 1610 in Rome, Goudt owned several of his pictures. Goudt made seven engravings of Elsheimer's paintings, which were crucial in spreading his influence, as very few of his paintings were viewable even by artists; as
