“ Eichendorff's development was even more strongly influenced by his sojourn in Heidelberg (1807) , where the triumvirate of romanticism, Görres, Arnim, and Brentano, had, in the "Einsiedler Zeitung", taken the field against pedantry and Philistinism. With the two last-named the young poet did not then cultivate a closer acquaintance — he certainly did so in 1809 at Berlin — but the lectures of the great Görres made a deep impression on him. Recommended by Count Loeben, Eichendorff's first poems were printed in Ast's periodical, among them the famous song "In einem kiihlen Grunde". ”
