Have the writers slipped little anachronisms or mistakes into the script to see if anyone is paying attention? In "The Eternal Fire" Gillian and Ben are in the labyrinth beneath the Roman bath. Gillian is looking at a Romanesque mosaic on the wall. Ben, more concerned with finding a way out, says something like "We don't have time to worry about some Egyptian art work!" [Loose paraphrasing, but the word 'Egyptian' definitely was in the sentence.]
In "Cradle of Civilization" the Iranian diplomat was bragging about the contribution the Babylonian civilization has made on Western cultures. Among a string of legitimate claims, he mentioned giving the West it's days of the week. Hang on! In the spirit of "every god must have his day," we know that English days of the week come from Nordic gods, and most Romance languages honor Roman gods during the week.
Did anyone, more astute in American history than I, catch any similar mistakes in "Warrior," or even the first episode?
