PLEASE HELP ME ANALYSE THIS PASSAGE from Antigone?

Question

Naturally! Since Zeus never promulgated such a law,

Nor will you find that justice,

Mistress of the world below,

Publishes such laws to humankind

I never thought your moral edicts had such force

They nullified the laws of heaven

Which unwritten, not proclaimed,

Can boast a currency that everlasting is valid,

An origin beyond the birth of man

And I, whom no man’s frown can frighten,

Am far from risking heaven’s frown by flouting these

I need no trumpeter from you to tell me I must die,

We all die anyway

And if this hurries me to death before my time,

Why such a death is gain. Yes surely gain

To one whom life so overwhelms

Therefore I can go to meet my end

Without a trace of pain

But had I left the body of my mother’s son unburied

Lying where he lay

Ah that would hurt!

For this, I feel no twinges of regret

And if you judge me fool perhaps it is

Because a fool is judge

LITERARY DEVICES?

Answer 1

I believe it shows Antigone follows the gods unwritten laws, rather than man's civic ones, such as Creon's edict.
