FOUR ZOAS IV / 51:21-53:24 The regressive desire for "sweet Science" reap- pears at the end of The Four Zoas. Like Ahania's in Night III, Tharmas'memory of a state of being prior to The Four Zoas narrative is nostalgia for his mar- ginal participation in Los and Enitharmon's pastoral wanderings (and sexual dialogue) in Night I. The Tharmas/Los power struggle: phase 2 The dialectical relation of Tharmas and Urizen continues. Los seems unaware that he is in any way under the power of Tharmas but focuses instead oni his own vengeance. retreats from asserting his authority; second, in the way his verbal retreat enacts a version of spatial fleeing; third, in the way his memory of the "Eternal fields" (51:21) and "sweet Science" (51:30) constitutes a retreat from the complexity of the present narrative into a fantasized pastoral landscape; and fourth, in the way he projects, for the third time, all guilt upon Urizen and Luvah. His compulsion to repeat this latter gesture reveals its significance as a suppression ofhis awareness of his own respon- sibility for the present narrative situation. Tharmas' final command to Los reveals that this third confrontation is actually a version of the initial clash between Tharmas and Los. In order- ing Los to take the hammer of Urthona and "rebuild these furnaces," reincarnating the most painful details of Urizen's architectural creation in Night II, the furnaces of affliction into which Luvah was cast, Tharmas asks, "Dost thou refuse mind I the sparks that issue from thy hair" (51:33). This image repeats Los's first response to Tharmas' advances: "Los answer in his furious pride sparks issuing from his hair" (48:11); "In scorn stood Los red sparks of blighting from his furious head" (48:25). Thus Tharmas first notices these sparks, which issue before the separation of Los and Enitharmon in the narrative proper, only after that separation has occurred. From Los's point of view Tharmas' blustering battle, which re-enacts the strife above the Body in Ahania's vision of Night II, is a fleeing. This departure of Tharmas from the narrative proper marks the return of Urizen, this time explicitly as a chaos. As Tharmas (the embodied character-form of Urizen's chaotic state) leaves, Urizen reappears to Los: "Los beheld the ruins of Urizen beneath / A horrible Chaos to his eyes. a formless unmeasurable Death" (52:11-12). The task that Los now begins -the rebuilding of the "furnaces," the final order Tharmas gave-is the way Los experiences his struggle with Tharmas: "he builded them anew / Labour of Ages in the Darkness & the war of Tharmas" (52:16-17). Los's action immediately returns the narrative to a strand of the action from Nights I and II: thejob of binding Urizen allows Los to fulfill the revenge he "plotted" against Urizen and Enitharmon in Night I (12:9), a revenge which has re-surfaced only once since then in Los's speech in Night II (34:50-53). A repressed aspect of Los has thus sought revenge against the formida- ble adversaries he has faced: the sexually absorbing female (Enitharmon, Vala) and the power-seeking male (Urizen, Luvah). Enitharmon's role as sexual accomplice of Los in dividing Urizen from Ahania by drawing Enion to Ahania dramatically turns back on her here. The male and female forms, who by their strength have previously crystallized Los's weakness, are now consolidated before the furnaces, equally at the mercy of Los. At this point the vengeful Los cannot make a distinction between sexual division and power division, but the Spectre, who is still haunted by "jealousy," can perceive the difference. Chains of fire automatically lash on to Enitharmon as Los begins to bind Urizen. Because he has vengefully
