[Question and a bit of a meta question] Did the Ancient Greeks have an equivalent exclamation to "Oh my God!"?

by TerkRockerfeller

My meta question ties into this: My class is putting on a play for Odyssey of the Mind based off the legend of Pandora's Box, and while it's supposed to be funny and lighthearted (the problem is to represent it as a video game, after all), we'd like to make sure it's at least somewhat accurate to the time/myth. Can/would anyone like to be our historical expert for small questions like this, and maybe a few proofreadings of the script? We'll credit you in the performance!
