Art Nouveau is set to meet pop culture on Sunday at a museum in the German city of Wiesbaden when Taylor Swift fans descend on the capital of the state of Hesse to view a painting that apparently inspired a song by the US pop diva. Numerous Swift fans, popularly known as Swifties, are anticipated at a special event at the Wiesbaden Museum focused on the Art Nouveau painting of “Ophelia” exhibited there.
