Since the sites went down around the time of Portal release, I would like to have a discussion about the imagery with you guys.
Anyways after playing through Portal I noticed the large amount of Greek Mythological references. I re-read Theogony and this is what I came up with.
1. If you find the turret that says 'I am different', you know the one you get an achievement for if you save it, if you hold onto it tells you stuff. First it tells you to remember Caroline, then it tells you about the story of Prometheus. This indicates that GLaDOS has some sort of relation to Prometheus.
2. When you find GLaDOS again as a potato she is being pecked at by a bird, just like Prometheus. The imagery is obvious to anyone.
3. GLaDOS was of course cast down a deep pit, which was the same punishment that Prometheus received.
4. One of the co-op partners names is Atlas, Atlas of course was brother to Prometheus.
5. The relation between Epimetheus and Wheatley seems to obvious and more than archetypal. You will remember that Wheatley at the end of Portal 2 laments what he did, and Epimetheus of course was the Titan of hindsight.
6. Wheatley reference, "Aristotle versus MASHY SPIKE PLATE!" and "Well, you know the old formula: Comedy equals tragedy, plus time."
7. GLaDOS lack of hindsight can be seen in the ending where when even after learning a leason decides to delete Caroline anyways, and Prometheus being of course the Titan of foresight.
These were the six references I found and this was my conclusion after reading Theogony:
