(4) Assyria and Troy:
In the Iliad, Homer uses the ancient Troy tradition
to tell of the struggle of the contemporary free Greeks against the Assyrian great kings.
He dismisses the painting of the heroic struggle of the free Achaians and Danaer against a despotic power doomed to destruction.
Homer does not write a key novel, he is a poet who wants to entertain and finds his motifs in contemporary history.
So the roles are sometimes reversed, then the mighty Assyrians become mighty Greeks, the great armies of the Assyrians become great armies of the Danaans, the Karatepe, which is inferior to the Assyrians, becomes Troy, which is inferior to the Greeks.
But mostly the Achaians and Danaans are the Greeks and the Assyrians the Trojans.
