_The Book of Los_ (engraved 1795) begins with the lament of Eno, aged Mother, as she recalls the "Times remote, when love and joy were adoration and none impure were deemed." For now, alas! Los, who alone could teach joy and liberty, is bound "in a chain and compelled to watch Urizen's shadow." Yet he cannot be bound for ever. Maddened by hard bondage, he rends asunder the vast Solid that has bound him, only to fall through the horrible void of error--"Truth has bounds, Error none"--till his contemplative thoughts arise and throw out some sort of standing-ground amidst the dire vacuity. Urizen by his contemplative thoughts, it will be remembered, had created "a wide World of solid obstruction." Now the two dæmons become rivals, and the grim conflict of the ages is waged incessantly. Los with hammer and tongs organizes lungs (understanding, see Swedenborg), and some Light even appears; but the book closes with no sign of the ultimate triumph of Los, for Los and Urizen are here rivals: there can be no victory until they cease to be rivals, and re-enter into the union of the eternal order.
_The Book of Ahania_ (engraved 1795) gives the story of Fuzon, Urizen's most fiery son, and therefore the one most obnoxious to his curse. He is mortally wounded by a poisoned rock hurled at his bosom from his father's bow, and his corse is nailed to the topmost stem of the Tree of Mystery, which is religion. Then follows the sad and beautiful lament of Ahania--the wife and emanation of Urizen, and mother of the murdered Fuzon. She recalls, like Eno, the former days, when Urizen stood in the divine order, and she, his lover and wife, joyed in the transports of love, when her heart leaped at the lovely sound of his footsteps, and she kissed the place whereon his bright feet had trod; when she knew the thrilling joys of motherhood, and nursed her Babes of bliss on her full breasts. These things were now but a memory. Urizen with stern jealous cruelty had put her away, compelling her to walk weeping over rocks and dens, through valleys of death, a shadow upon the void, and on the verge of nonentity, a deep Abyss dividing her from her eternal love. Thus she weeps and laments, wearing a sorrow's crown of sorrows, the remembering happier things.
