[Hayy grows up nursed by the Roe.]
According to the other account (which we follow) the infant developed and grew, being nourished with the roe’s milk, until he was two years old. By this time he began to walk by degrees and grow his foreteeth. He always followed the roe, who guarded him with most tender affection, and led him into places where there grew trees full of fruit, and fed him with ripe and sweet fruits that fell from the tree, breaking those that had a hard shell with her teeth.
She suckled the babe whenever he pleased. When he thirsted for water, she led him thereto; when the beams of the sun were in any way troublesome to him, she shaded him. When he suffered from the cold, she cherished and warmed him. And when the night approached, she brought him home to his former abode and covered him with her own body and partly with feathers such as remained of those wherewith the ark was stuffed when he was first put into it. When they went forth in the morning or came home of an evening, they were always accompanied by a herd of deer that lay together with them, in the same place.
[Hayy learns to imitate animals’ voices.]
In this way the boy keeping company with them also learned their voice, which he imitated so exactly that scarcely any difference could be perceived between them. In like manner, whatever other voice he heard, whether of bird or beast, he came very near it by virtue of a very apprehensive faculty wherewith he was endowed. But of all the voices he imitated, he made most use of the deer’s when they cried out for help or called their fellow-deer, when they wanted them nearer by or farther off. For as you know, those creatures have diverse voices according to their various ends and uses. Thus the child kept company with the deer, and they were not in the least afraid of one another.
[Hayy begins to take a careful view of things.]
Now when the images of things, after being removed out of sight, became fixed in his mind, it affected him so that he took a fancy to some things, whilst he had a distaste for others. In the meanwhile he took a careful view of all the beasts. He saw them covered with wool, hair, and different kinds of plumes; he beheld their great swiftness and strength and the weapons they were armed with for protection and defence, viz. horns, teeth, hoofs, spurs, nails, and the like. Then he viewed himself and found he was naked, destitute of weapons, slow and weak. For whenever they contended with him about the fruits they were to feed on, he generally got the worst of it; they pulled the fruit from him, keeping it for themselves, and he could not beat them off or flee from them.
[Hayy observes the difference between the animals and himself.]
Moreover, he observed that his fellow-fawns began to have little horns which they had not had at first; and while they were at first weak, and unable to run far, yet in progress of time grew to be very vigorous and nimble, and active in their movements. But none of all this he perceived to befall himself, and as often as he pondered over the matter, he could not make out what should be the reason thereof.
Also, when he beheld the creatures such as had any fault or defect of limbs, he could not find one amongst them like himself. All these matters evoked great grief and anxiety within him; and after having earnestly pondered over the matter and perplexed himself therewith, he at last gave up, in utter despair, the hope of being supplied with that, the want of which so sorely troubled his mind.
