Tonio Kröger forms a pair with the more famous story, Death in Venice (Der Tod in Venedig). They both describe the life of an artist and express Thomas Mann's views on art. In one story the artist travels from south to north, in the other from north to south. One journey ends in a tenuous reconciliation, and the other in death. But, as T. J. Reed has pointed out,

Thus the importance of the work lies, chiefly, in its autobiographical character, as well as in its contribution, through the description of an amitié particulière, to the theory of love.
The novel was made into a film in 1964, directed by Rolf Thiele.[5]
