Dan... that could make one think for days about the meaning of the possible "heavy eroticism" noted by ake. I went in a different direction as the genitals puzzle me. The female form coming to the fore over time and then the torso and "lower parts" obviously torn asunder with male genitals and bones, a rib, isolated in time and space whilst a dog ravages... a dog of war?... the embodiment of the war between the sexes over time with time being the central focus? eternal strife between the sexes???
