The line starts with 'O Soma Luce', which is the title of the movie and the 67th line of Dante's 33rd song 'Heaven' in 'Divine Comedy', until the end of 'Heaven'. This movie is written with music and lines, rather than emotions and narrative. This is the latest attempt to combine film with literature. The film opens with a black screen and music by Edgar Varese. BGM was recorded in 1954 as' Desert '. After a period of darkness, the music ended and a middle-aged man sat on the mountain reciting something. He is Italian literature professor George Pacelon, who is reading the last part of "Heaven" in Dante's Divine Comedy. Jean Marie Straub expressed his views on Dante with a subtle accent and dialect. This director coded for many great artists and musicians, including Bach, and completed the combination of Dante and Varese, which may seem strange. (Lin Jingyong)
