These are the first lines of Herodotus' Histories. So these lines are known as Histories I, 1-6. They tell an alternative story about the outbreak of the Trojan war.
This is the text of the inquiry of Herodotus of Halicarnassus, so that things done by man may not be forgotten in time, and that great and marvelous deeds, some displayed by the Hellenes, some by the barbarians, not lose their glory, including among others what was the cause of their waging war on each other.
The Persian learned men say that the Phoenicians were the cause of the dispute. These (they say) came to our seas from the sea which is called Red,1 and having settled in the country which they still occupy, at once began to make long voyages. Among other places to which they carried Egyptian and Assyrian merchandise, they came to Argos, [2] which was at that time preeminent in every way among the people of what is now called Hellas. The Phoenicians came to Argos, and set out their cargo. [3] On the fifth or sixth day after their arrival, when their wares were almost all sold, many women came to the shore and among them especially the daughter of the king, whose name was Io (according to Persians and Greeks alike), the daughter of Inachus. [4] As these stood about the stern of the ship bargaining for the wares they liked, the Phoenicians incited one another to set upon them. Most of the women escaped: Io and others were seized and thrown into the ship, which then sailed away for Egypt. 2.
In this way, the Persians say (and not as the Greeks), was how Io came to Egypt, and this, according to them, was the first wrong that was done. Next, according to their story, some Greeks (they cannot say who) landed at Tyre in Phoenicia and carried off the king's daughter Europa. These Greeks must, I suppose, have been Cretans. So far, then, the account between them was balanced. But after this (they say), it was the Greeks who were guilty of the second wrong. [2] They sailed in a long ship to Aea, a city of the Colchians, and to the river Phasis:2 and when they had done the business for which they came, they carried off the king's daughter Medea. [3] 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. 3.
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 Hellas by capture; for he was confident that he would not suffer punishment. [2] 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. 4.
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 before the Persians attacked Europe. [2] “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. [3] We of Asia did not deign to notice the seizure of our women; but the Greeks, for the sake of a Lacedaemonian woman, recruited a great armada, came to Asia, and destroyed the power of Priam. [4] Ever since then we have regarded Greeks as our enemies.” For the Persians claim Asia for their own, and the foreign peoples that inhabit it; Europe and the Greek people they consider to be separate from them. 5.
Such is the Persian account; in their opinion, it was the taking of Troy which began their hatred of the Greeks. [2] But the Phoenicians do not tell the same story about Io as the Persians. They say that they did not carry her off to Egypt by force. She had intercourse in Argos with the captain of the ship. Then, finding herself pregnant, she was ashamed to have her parents know it, and so, lest they discover her condition, she sailed away with the Phoenicians of her own accord. [3]
These are the stories of the Persians and the Phoenicians. For my part, I shall not say that this or that story is true, but I shall identify the one who I myself know did the Greeks unjust deeds, and thus proceed with my history, and speak of small and great cities of men alike. 6.
As you can see, Helen is still the issue in Herodotus' version of events, but she is just one in a series of abductions. A Phoenician ship abducted Io, and then a Greek ship abducted a Phoenician princess called Europa. Then another Greek ship abducted Medea from Colchis. This is followed by the abduction of Helen by a Trojan prince, in retaliation for the abduction of Medea. Thus there were retaliatory abductions of high status women going on.
The usual story of how Medea left Colchis is, of course, the story of Jason and the Argonauts, in which Medea uses her magical powers to help Jason steal the golden fleece from her father, a powerful sorcerer, then flees to Greece aboard the Argos with Jason and her brother. This is no abduction because she goes willingly, eventually marrying Jason and becoming his queen when he takes the throne. Similarly, the usual story is that Helen, the queen of Sparta, fell in love with Paris, a mere prince, via the agency of Aphrodite, and went with him willingly to Troy.
Meanwhile, Io is one of many mortal women with whom Zeus fell in love. He turned her into a cow to hide her from his jealous wife. After many adventures he turned her back into a human.
