Nick Vivarelli International Correspondent Roughly two years after his return to Naples for “The Hand of God,” Paolo Sorrentino is heading back to his hometown for a movie that plays on local mythology. The still untitled film is about a woman named Partenope “who bears the name of her city but is neither siren nor myth,” the Oscar-winning auteur has revealed to Variety. In Greek mythology, Parthenope, as she is known in English, is the name of a siren who having failed to entice Odysseus with her songs, cast herself into the sea and drowned. Her body washed up on a symbolic foundational rock where Naples lies. Neapolitans in Italy are also known as “Parthenopeans.”
