Friedrich exhibits Cross in the Mountains in his apartment over Christmas – generating controversial reactions, 1808

Basilius von Ramdohr publicly criticizes the painting later known as the Tetschen Altar. In response, Friedrich writes a letter in which he explains both his motivations and his artistic principles in detail. Others also publicly express their support for Friedrich. The so-called Ramdohr dispute illustrates the divergent views prevailing at the time regarding secular art – exemplified here by landscape painting – and sacred art.
