" Santi was a behemoth in the art world, and being known solely by one's first name was a level of fame achieved only by an elite few... people like Napoleon, Galileo, and Jesus... and, of course, the demigods Langdon now heard blaring from Harvard dormitories - Sting, Madonna, Jewel, and the artist formerly known as Prince, who had changed his name to the symbol ?, causing Langdon to dub him 'The Tau Cross With Intersecting Hermaphroditic Ankh. "

― Dan Brown , Angels & Demons (Robert Langdon, #1)
