From Tablet I
"In the wildness(?) she created valiant Enkidu,
born of Silence, endowed with strength by Ninurta.
His whole body was shaggy with hair,
he had a full head of hair like a woman,
his locks billowed in profusion like Ashnan.
He knew neither people nor settled living,
but wore a garment like Sumukan."
He ate grasses with the gazelles,
and jostled at the watering hole with the animals;
as with animals, his thirst was slaked with (mere) water."
The comment about the whole body shaggy with hair makes me wonder if this might be the earliest record of Asian Almas.
Anyhow there have been many books written about various cases of feral children. Attempts to bring them into society have met with limited success. The one common theme seems to be that development of language is often suppressed. It would seem that there is a time window of development in children that allows verbal skills to develop and if those skills are not developed at that time then later attempts never can develop a full vocabulary.
