History of the Peloponnesian War

And being now more in this state of things, some time after they made the expedition against Troy.

And Agamemnon appears to me to have assembled the armament because he surpassed the men of that day in power, and not so much because he took the suitors of Helen bound by their oaths to Tyndarus.

It is said too by those of the Peloponnesians who have received the most certain accounts by tradition from their forefathers, that Pelops first acquired power by the abundance of riches with which he came from Asia to men who were in needy circumstances; and although a new-comer, yet gave his name to the country; [*]( Or more literally, gave occasion to the naming of the country after him. ) and that afterwards still greater power fell to the lot of his descendants, as Eurystheus was killed in Attica by the Heraclidae, and Atreus was his mother's brother, and Eurystheus, when going on the expedition, intrusted Mycenae and the government to Atreus, on the ground of their connexion; (he happened to be flying from his father on account of the death of Chrysippus :) and when Eurystheus did not return again, they say that at the wish of the Mycenaeans themselves, through their fear of the Heraclidae, and also because he appeared to be powerful, and had courted the commons, Atreus received the kingdom of the Mycenaeans and all that Eurystheus ruled over; and that so the descendants of Pelops became greater than those of Perseus.

And I think that Agamemnon, from having received this inheritance, and from being strong in his navy also at the same time to a greater extent than others, assembled and made the expedition not so much by favour as by fear.
