Gonna second the other two comments, but I think its worth remembering that the warrior society of Sparta likely never existed. People didnt start talking about the indomitable martial society of Sparta until, like, 300 years after the nation of Sparta stopped existing. Contemporary accounts seem to tell that Spartan society looked pretty similar to other Greek states at the time, except they actually trained their soldiers. For example, the agoge now has a reputation as the brutal training ground where Spartan boys became men, but contemporary accounts say that their boys were not just trained in martial arts but also in hunting, dancing, singing, reading and writing, and rhetoric. It wasnt until the roman empire gave them a tourist industry that they started playing up the "legendary honorable warrior culture" angle, partially as a conservative movement calling to return to the good old days where men were real men.

give it a rewatch, tell me if you notice them.
