As time went by, he and his wife, Heva, came to reside in the Vales of Har, where they gradually succumbed to dementia, regressing to a childlike state to such an extent that they came to think their guardian, Mnetha, is their mother, spending their days chasing birds and singing in a "great cage" (Tiriel; 3:21).
Later, after Tiriel has had most of his own children killed, he returns to the Vales with the express purpose of condemning his parents and the way they brought him up, declaring that Har's laws and his own wisdom now "end together in a curse" (8:8); The child springs from the womb.
the father ready stands to form The infant head while the mother idle plays with her dog on her couch The young bosom is cold for lack of mothers nourishment & milk Is cut off from the weeping mouth with difficulty & pain The little lids are lifted & the little nostrils opend The father forms a whip to rouze the sluggish senses to act And scourges off all youthful fancies from the newborn man Then walks the weak infant in sorrow compelld to number footsteps Upon the sand.
Such was Tiriel Compelld to pray repugnant & to humble the immortal spirit Till I am subtil as a serpent in a paradise Consuming all both flowers & fruits insects & warbling birds And now my paradise is falln & a drear sandy plain Returns my thirsty hissings in a curse on thee O Har Mistaken father of a lawless race my voice is past[1] Upon this declamation, Tiriel then dies at their feet.
In the Africa section of the later poem The Song of Los (1795), which is set chronologically before Tiriel, Har and Heva are forced to flee into the wilderness, after their family rebel against them.
Because their brethren & sisters liv'd in War & Lust; And as they fled they shrunk Into two narrow doleful forms: Creeping in reptile flesh upon The bosom of the ground:[7] Damon refers to this transformation as turning them into "serpents of materialism," which he relates to their role in Tiriel.
