2,000 years ago, maybe. The meaning of the word saint changed over the years to mean a sort of influential spiritual paragon, allowing us apply it to cultures don't have the same language but have http://en.wikipedia.org/wiki/Sword_saint. Saints have the same meaning they have in the modern era in Morrowind, as sacred persons and models of behaviour. They're very much like the Catholic saints too, in that they can represent both qualities and occupations.
And only Catholicism in that light. But then, you can't consider the religion presented in the game Morrowind without the parallels of the religion they modeled it on.
I'm thinking more http://www.dkimages.com/discover/previews/832/35062844.JPG. Isis was also sometimes depicted with wings. Cultural exchange is not out of the question, though. The Egyptians even adopted some Sumerian gods, like Ishtar/Innana.
Mesopotamia? What year? I was thinking Zoroaster with the greek influence (winged messangers, whatnot) in the fifth century on the other side of the calendar.
We could wipe that all away with the ?atal H?y?k angle, but those would be guesses based on what we think they would be.
'Angels' are compatible with ancestor worship, since they'd be ascended spirits who've got it good in the afterworld.
I've never heard of a culture that takes this view on things. Which is it?
