So recently we were told of the Engineer's society being based on the Persians. So, I decided to do some wiki research and cross-reference, when I come up with this fellow;
http://en.wikipedia.org/wiki/AeschylusSeems this fellow wrote plays, including
The Persians, a play about how a King's pride leading to loss from hubris and angering the gods...
Also he wrote
Prometheus Bound, enough said about that story, I think
So, could the survivor Engineer be close to Xerxes, a son of the Elder Darius, or could it be instead another person in the film? Either way, Xerxes played a rather Prometheus-like role in The Persians.
Theories welcome as always
