The major of the City of New York took issue with a number of works in a Brooklyn Museum temporary exhibit title "sensation: Young British Artists frrm the Saatchi Collection." Especially troubling to him as a painting by Nigerian artist Chris Ofili, entitled "The Holly Virgin Mary." In that work, Ofili depicted Mary with African features and attached a clump of elephant dung as well as photographs of female genitalia to his work. The mayor termed Ofili's painting "sick" and "disgusting." He insisted that a city-supported museum had no right to display the exhibit.
