It was originally planned to have concluded by contrasting the sacred nature of an adagio movement entitled "Caritas" with a setting of the pagan hymn "The Birth of Eros." One of its movements is a setting of a Latin song written in the 9th century by Rabanus Maurus. The two movements of this symphony are connected by the "Accende lumen sensibus" theme, which comes from the fourth stanza of the hymn that its first movement is a setting of, the "Veni, creator spiritus." This symphony was promoted and nicknamed by Emil Gutmann and its second movement includes a chorus of the Anchorites and soloists voicing the characters Doctor Marianus and Gretchen. It was inspired by Goethe's Faust and included three choirs at its premier. For 10 points, name this massive symphony of Gustav Mahler.
