 The triptych is further distinct in that its creatures are located in an outside space; by 1948, Bacon's studies of heads and figures specifically emphasised their confinement in rooms or other closed spaces.Although Bacon stated that he modelled the creatures on the Furies, the visual link to the sources is barely perceptible in his finished work.The mood and tone of the painting, however, is consistent with the agonized spirit of the Furies' legend.
