The Question Mark Inside

Mark Wallinger's Echihomo was initially displayed in Trafalgar Square on the fourth plinth. It later had a second outing to the West End of St Paul's Cathedral. And if you look in the molding in the archway above the window, you can see that she's echoed almost the exact same oval shape that's already there for God. This is the kind of work that I think is plenitudeiness, it rewards repeated long contemplation.
