His stay in Venice is undocumented, but the influence on his style is clear. He probably worked as an assistant to Johann Rottenhammer, some of whose drawings he owned. Rottenhammer was a German who had been living in Italy for some years, and was the first German painter to specialize in cabinet paintings. Uffenbach had specialized in large altarpieces, and although Elsheimer's earliest small paintings on copper seem to date from before he arrived in Italy, Rottenhammer's influence is clear on his mature work.
