St Stephen's Green is a public park in the center of Dublin, populated with memorials to famous Irishmen and one standing figure in bronze by Henry Spencer Moore (1898-1986). Moore's figure looks like an assemblage of birds' bones in vaguely human form, with a small stub of a head and a knife-edge torso turning at the hips. Unlike sculptures with more recognizably human features, it is impossible to guess what the figure looks like on its far side. The only way to find out is to walk around it. According to Moore, this is the one great advantage that sculpture has over painting— it can be looked at (and, in the case of Moore's sculptures, must be looked at) from all round.
