The Histories · 7.151

Also some of the Hellenes report that the following event, in agreement with this account, came to pass many years after these things:--there happened, they say, to be in Susa the city of Memnon envoys of the Athenians come about some other matter, namely Callias the son of Hipponicos and the others who went up with him; and the Argives at that very time had also sent envoys to Susa, and these asked Artoxerxes the son of Xerxes, whether the friendship which they had formed with Xerxes still remained unbroken, if they themselves desired to maintain it, or whether they were esteemed by him to be enemies; and king Artoxerxes said that it most certainly remained unbroken, and that there was no city which he considered to be more his friend than Argos.
