Friedrich is recognized today as the supreme German painter of the Romantic era, but in his own time his genius was not so widely acknowledged. This was not because the aims of his art were foreign to the interests of his generation. On the contrary, his allusions to the spiritual in nature, his close study of the local landscape, and his emphasis on the need for inspiration were all commonplace preoccupations of the period. His art was undervalued because it explored these areas with a new uncompromising vision that was too personal and original to be easily grasped.
