FOUR ZOAS VIIA / 77:27-80:43 How contextually "new" elements make possible the transforma- tion and re-surfacing of prior elements is dangerous to refer to any elements as wholly "new." In Nights VIIa, VIIb, and VIII, however, new names appear, associated with decisive and significantly new roles. These contextually new structures both evolve out of prior interconnected transformed structures and are made possible by means of the re-surfacing of the previously suppressed structures. The principal new figures in these later Nights are the "Shadow of Enithar- mon" (in her tryst with the Spectre of Urthona and in her ambiguous transformation into the "Shadowy Female"); "Rahab" (and Tirzah); the "Synagogue of Satan"; and the "hermaphrodite." These structures are among the most difficult and perplexing in the poem. Though they emerge out of the context of overlapping and re-surfaced structures, they are simultaneously the cause and the effect of the pervasive perceptual confusion and "delusion" that hover over these Nights. While the imagery of the Tree of Mystery, the war, and weaving is tightly interlocked into a structure, Orc's division into serpentine and spectrous forms develops into a confusion between the Lamb of God and Satan and between Jerusalem and Rahab. Now we must see how this confusion becomes possible. The Shadow of Enitharmon Urizen brings the Shadow of Enitharmon into existence as he reads from his book of brass (see above, pp. 245-47). Orc's serpent form as one way Urizen per- ceives the Shadow of Enitharmon Perceptual Structures of the Shadow. The structural complex Blake names "The Shadow of Enitharmon" enters the poem amid extreme nar- rative and syntactic ambiguity. The Orc/Urizen confrontation, toward which Urizen felt his journey in Night VI was proceeding as if it were to be a monumental event, actually turns out to be an anti-climax in the extended version of Night VIIa. Even in Blake's early version of VIIa, which ended after the dead burst from the bottoms of their tombs and the Spectre gives control of "howling Orc" to the "lovely shadow," the con- frontation between Orc and Urizen is overshadowed by the meeting be- tween the Spectre of Urthona and the Shadow of Enitharmon, which the Orc/Urizen interchange makes possible. Ironically, but inevitably, the Shadow ofEnitharmon first appears in Urizen's hypocritical speech to Orc as a sexual aspect of Urizen's preaching his rules of morality: "let Moral Duty tune your tongue / But be your hearts harder than the nether millstone / To bring the shadow of Enitharmon beneath our wondrous tree / That Los may Evaporate like smoke" (80:3-6). Urizen sees the division between "tongue" and "heart" (which, as noted earlier, thrives on the internal division of Urizen in simultaneously acknowledging and re- pressing the book of iron) as a method of luring down the Shadow. There is no evidence, however, that Urizen can perceive the descent of Enithar- mon's Shadow as such: rather, he identifies Orc undialectically as Luvah when he sees the serpent form of Orc. Structurally, Orc's serpent form and Enitharmon's Shadow are direct aspects of each other, for both appear simultaneously as narrative reflexes to Urizen's hypocritical morality. On the one hand, Orc's serpent form is
