How did Adam Elsheimer influence Claude Lorrain’s small paintings on copper?

The German artist Adam Elsheimer exerted a notable influence on the early career of Claude Lorrain. During his early period in Rome, Claude produced small, intricate paintings on copper that reflected the spirit of Elsheimer’s work.1

Elsheimer was renowned for his own small, detailed paintings on copper, which often featured expressive and mysterious lighting effects, including the innovative use of firelight and candlelight. By adopting this medium and approach, Claude’s early works captured a similar charm and sense of surprise, characterized by animated, picturesque compositions that preceded his later, more monumental Classical style.21
