Apart from his many scientific publications and his poetry, Kerner was also the author of one of the more intriguing literary works of German Romanticism, Die Reiseschatten (Travel Shadows, 1811). Ostensibly an account of his travels through Germany and Austria following his graduation from the University of T├╝bingen, the book is a highly imaginative, almost surreal concoction of Romantic, sentimental, grotesque, satirical, and Old German folkloric elements. Attributed by Kerner to an itinerant тАЬshadow performerтАЭ named Lux, Travel Shadows was inspired by the tradition of тАЬChinese ShadowsтАЭ (ombres chinoises) and represents KernerтАЩs attempt to create a travel narrative in the form of a grandiose shadow show.
In the introduction to his translation of Travel Shadows тАУ the first in English тАУ Harold B. Segel situates KernerтАЩs work in the context of the emergence of a German shadow show tradition in the nineteenth and twentieth centuries.
