The whole world does not contain such wealth or such fine lands that we would accept them in payment to join Persia and enslave Greece. So much forbids us, and not least the burning of the temples and the statues of our gods, now nothing bu dust and debris. To avenge such violation, not to clasp the hands of those who did it, is our duty. It would be shameful to betray the Greeks, our people, united in one blood, one language, in our temples and our rituals, our common customs. So, know this: as long as there is one Athenian left on this earth alive, we shell never make peace with Xerxes.
I believe this is very touchy. Since the time when money, trade and wealth were ‘invented’ people did already know that the most important things in life cannot be traded. There are things that matter more than money.
