Older Than They Think:
- A number of lines from the movie are actually from Herodotus, including "fight in the shade" and "Tonight, we dine in Hades" (Hades was the underworld, or Hell, for Ancient Greeks). The Spartan epitaph planted by the side of the road is actually still visible as a marker from the Classical period:
Go tell the Spartans, passer by,
That here, by Spartan law, we lie.
- Queen Gorgo also apparently said "Only Spartan women give birth to real men." Though this is believed to have been said to another Greek, not to a Persian Messenger.
