When the Colchian king sent a herald to demand reparation for the robbery and restitution of his daughter, the Greeks replied that, as they had been refused reparation for the abduction of the Argive Io, they would not make any to the Colchians.
Then (they say), in the second generation after this, Alexandrus, son of Priam, who had heard this tale, decided to get himself a wife from Greece [22,39] (nation), Europe Hellas by capture; for he was confident that he would not suffer punishment.
So he carried off Helen. The Greeks first resolved to send messengers demanding that Helen be restored and atonement made for the seizure; but when this proposal was made, the Trojans pleaded the seizure of Medea, and reminded the Greeks that they asked reparation from others, yet made none themselves, nor gave up the booty when asked.
So far it was a matter of mere seizure on both sides. But after this (the Persians say), the Greeks were very much to blame; for they invaded Asia (continent)Asia before the Persians attacked Europe (continent)Europe.
“We think,” they say, “that it is unjust to carry women off. But to be anxious to avenge rape is foolish: wise men take no notice of such things. For plainly the women would never have been carried away, had they not wanted it themselves.
