A quote from Life Site News, 26 March 2008

The Dommuseum in Vienna, the art gallery attached to the historic Catholic cathedral of St. Stephen, is running an exhibition of works by a self-avowed Marxist atheist [Alfred Hrdlicka], titled “Religion, Flesh and Power”, that includes depictions of explicit homosexual sex acts in “religious” themed art. Prominent among the works is a rendition of the Last Supper with Christ and His Apostles depicted as homosexuals engaged in an orgy. […]  The director of the Dommuseum, Mr. Bernhard Böhler, said that visitors have asked “in a more or less emotional way,” why the Apostles are depicted copulating. According to the director, the artist responded, “There were no women around”.

Gloria Television made a short video of the works that shows Hrdlicka’s depiction of the flagellation of Christ with a nude Roman soldier performing a lewd act on the Lord's body. […]
 
Vienna’s Cathedral and Diocesan Museum was founded in 1933, and describes itself as “one of the exquisite gems amongst the many museums in Vienna”. It is located adjacent to the Archbishop’s Palace of Christoph Cardinal Schönborn, O.P.
