CONTEXTUAL STRUCTURES Inclusion or omission of Vala and ofLuvah's robes of blood marks the causal inversion of the two primary brackets. "Eternity" as a narrative fiction susceptible to the laws of perspective transformation Within the second primary bracket (Eternity) further embedded struc- tures occur, but these structures are not marked by repeated lines. The Eternity bracket divides into two sub-phases-a long speech delivered by "messengers from Beulah" and an account by the narrator proper of the actions of the Daughters of Beulah. The messengers' account reverses the order in which information was generated in the Tharmas/Enion bracket: in the messengers' account, the primary conflict occurs between Urizen and Luvah (who functioned as derivative characters in the Tharmas/Enion plot); in the messengers' account the conference and combat between Urizen and Luvah is ontologically and narratively primary and generates the sexual division of Tharmas and Enion; at the same time, however, the messengers' report inadvertently presupposes that division. In addition, the absence from the messengers' account of the character Vala and the key image of"Luvahs robes of blood," whether through ignorance or suppres- sion, accompanies an inversion of the narrative/ontological field. At least at one stage of the text's evolution, Blake specifically revised the first part of Night I by deleting an extended conversation between Enion and the Spectre regarding Enion's slaying of Emanations.6 Therefore, at the one point where the two primary brackets of Night I could intersect or overlap (at Enitharmon's causal relationship to Tharmas and Enion [22:22-23]), the reader is confronted with an inversion of narrative "facts." The narra- tor's account in the first bracket of Night I is incommensurate with the messengers' narration in the second bracket because the elements of expla- nation are no longer ontologically the same, even though they bear the same names. The second sub-phase of the "Eternity" bracket features the re- turn of the characters named the "Daughters of Beulah" and thus reintro- duces as the primary generative force the sexual plot which the messengers have just treated as secondary; like the messengers' account, however, the Daughters' segment also omits reference to Vala or Luvah's robes. The information generated from the perspective of Eternity and the information located textually prior to it and generated directly from the narrator in the Tharmas/Enion bracket invert one another. Because both phases of the Eternity bracket repress Vala and the key image of"Luvahs robes," however, this second primary bracket cannot be a source of unequivocally true or context-free information, obeying Blake's narrative ontology that dialectically conditions information so that it is primarily constituted by context. The gap between the Tharmas/Enion and Eternity perspectives derives from a radical ontological shift that totally reor- ganizes the narrative field and alters the meaning of characters and events. The disjunctive narrative fields of the first and second primary brackets of Night I thus subvert (by their mutual inversion) the possibility of an underlying stable world that is being distorted and rearranged by the surface text. Had Blake reversed the narrative order of the two primary brackets and given "Eternity" linear priority, it would have drastically altered the expe- riential (and thus ontological) status of these two segments.
