Thanks. You can probably tell, but it's more than a mere poem. It's an interpretation of the BIble verse at the beginning. I have wondered for some time if their "eyes" being opened is also a deeper metaphor for the birth of their egos and consequently them now considering themselves to be "I's."
fig leaf
noun
a leaf of a fig tree, often used for concealing the genitals in paintings and sculpture.
a thing intended to conceal a difficulty or embarrassment.
"the amendment was just a fig leaf intended to cover the cracks in the party"
The next passage says they made aprons from fig leaves. Which I think this definition suggests may mean more than covering up flesh, but the parts of ourselves we're ashamed to reveal to others.
