STRUCTURAL INTERFERENCE The openness of Blake's text to alternative struc- tural divisions A range of narrative characteristics that inter- fere with linear and/or embedded structures 6) and finally, the structure constituted by the story of Tharmas and Enion as children (130:2-131:19), existing within all of the above structures as the most deeply embedded structure of Night IX. In a two-dimensional map these bracketed structures enclose one another in symmetrical fashion (see Fig. D.1), although they could be visualized as a series of receding plane surfaces, with the movement from one bracket into the next involving a movement into a different reading surface constituted by its perspective. By incorporating into the poem details geared to a linear reading that directly conflicts with Night IX's embedded structures, Blake resists the temptation to render these elegant structures rigid, thereby retaining an extraordinary degree of narrative freedom in the context of precise structural constriction. These conflict- ing modes of organization strategically interfere with the reader's attempt to grasp Night IX even in the unconventional terms of the previous Nights. The particular dimensions of this internal narrative conflict radically keep open legitimate alternative ways of dividing or bracketing the text of Night IX. Any such alternative structuring of Night IX would, of neces- sity, rearrange the ontological/perspectival constitution of narrative events. For the purposes of our subversive reading, however, it is more useful to entertain the fiction that the symmetrical bracketed structures outlined above are stable divisions of the text against which contrary clues -for example, the feast as an aspect of the feast bracket as opposed to the feast as an aspect of the Eternal Man bracket-function as strategies of interference which force the reader's imagination to an unrelieved crisis. Preliminary Analysis of the Structural Interferences in Night IX Some of the features of Night IX that tend to obscure the embedded structures include: 1) the structurally eccentric placement of events such as the union ofTharmas and Enion, which has the potential to be Night IX's central resolving narrative event; 2) linear override plots which seem to proceed with relative indifference to embedded structures; examples include: the unfolding fate of the trumpet sound which eventually constitutes a circularity; the linear reappearances of the images of flames/fire (and their relation to consummation/consuming) and the harvest (in relation to the agricultural override plot); and the operation of the feast and Luvah/ Vala as linear plots as distinguished from their function as embedded structures; 3) pseudo-symmetrical structures, such as the parallel between Luvah and Vala in the garden and in the wine presses or between Tharmas and Enion in the garden and in their embrace;
