When all the ships had arrived at Aegina, there came to the Greek quarters messengers from the Ionians, the same who a little while before that had gone to Sparta and entreated the Lacedaemonians to free Ionia. One of these was Herodotus the son of Basileides. These, who at first were seven, made a faction and conspired to slay Strattis, the tyrant of Chios, but when their conspiracy became known, one of the accomplices having revealed their enterprise, the six who remained got them secretly out of Chios, from where they went to Sparta and now to Aegina, entreating the Greeks to sail to Ionia. The Greeks took them as far as Delos, and that not readily, for they, having no knowledge of those parts and thinking that armed men were everywhere, feared all that lay beyond. They supposed too that Samos was no nearer to them than the Pillars of Heracles. So it happened that the barbarians were too disheartened to dare to sail farther west than Samos, while at the same time the Greeks dared to go at the Chians' request no farther east than Delos. It was fear which kept the middle space between them.
