FOUR ZOAS VIIA / 77:5-78:19 (54:18-105:23) Schematic for Night Vila (Fig. C.1): pp. 330-31; for Night VIIb (Fig. C.2): pp. 334-35; for Night VIII (Fig C.3): pp. 338-39. Urizen's vision of Orc realizes in the narrative proper Ahania's account of Urizen's subservience in Night III. The Tree of Mystery mystifies Urizen's per- ception of Orc. those elements transformed from other Nights allow previously frozen terms (such as Spectre of Urthona, Lamb of God, Satan, and Vala) to re-surface into the narrative proper; 3) how the surfacing of these previ- ously suppressed elements of earlier Nights gets bound up with the intro- duction of apparently new elements (such as the Shadow of Enitharmon, Rahab and Tirzah, the hermaphrodite, and the Synagogue of Satan); and 4) how Blake organizes these conflicting and overlapping elements into particular experiential structures by giving them a certain order and grouping.' Overlapping Narrative Elements The Tree of Mystery When, early in Night VIIa, the "Tree of Mystery" suddenly materializes in the context of Urizen's confrontation with Orc, it seems to be a radi- cally new element in the poem. As Urizen descends from his war against the Spectre and Tharmas, he distinctly sees a constellation of plot elements which he had previously believed were under his control, including the tools and animals he commanded in the creation of the Mundane Shell in Night II (24:9-25:5): all these elements are now, however, bound up with Orc's fiery image. This scene projects into the narrative proper Ahania's visionary warning to Urizen in Night III (39:1-14) that Luvah was already in control of the steeds, tygers, and lions of Urizen and was thus already Urizen's master. In Night VIIa Urizen's unconscious defensive reflex to this ego-damaging information now appearing before him in the narrative proper generates the Tree of Mystery which surrounds him, shuts off his vision of Orc, and encloses his "book of iron"--the "dreadful letters" Urizen "trac[es]" as he tries to "cool the flames of Orc" (78:2-3). Urizen's book has taken on the characteristics of the "iron pen" with which he inscribed the "books" that remained as a defensive linear stay against his cyclic journey through Night VI (71:35-ff). The Tree of Mystery thus enters the poem as an image of perceptual repression, or, more accurately, of defensive perceptual mystification. Prior to the springing up of the Tree which entangles the book of iron within its labyrinthine branches, Urizen cannot speak to Orc. After the Tree appears, Urizen is able to address Orc, and the previously neutral unspecified "rock" Urizen has been sitting on absorbs the characteristics of his book and itself becomes a "rock of iron" (78:14) and an "iron Crag" (78:16). Before the Tree appeared Urizen directly perceived the cave filled with beasts and tools; after the Tree has appeared Urizen says to Orc, "No other living thing / In all this Chasm I behold" (78:18-19). Either Urizen is being blatantly hypocritical (and there is little indication that this is the case) or the Tree has made it possible for Urizen to repress the most immediately disturbing feature of Orc. The Tree of Mystery thus conceals
