For the 1893 Hamburg and 1894 Weimar performances, Gustav Mahler gave the piece the title "Titan" after the novel by Jean Paul (1763-1825), although Mahler specified that the piece was not in any way 'about' the book.
Some modern performances and recordings give symphony No. 1 the title 'Titan', despite the fact that Mahler only used this label for the two early performances and never after the work had reached its definitive four-movement form in 1896.
