When Aristagoras heard that, he went away to Miletus in great joy. Artaphrenes sent a messenger to Susa with the news of what Aristagoras said, and when Darius himself too had consented to the plan, he equipped two hundred triremes and a very great company of Persians and their allies in addition. For their general he appointed Megabates, a Persian of the Achaemenid family, cousin to himself and to Darius. This was he whose daughter (if indeed the tale is true) Pausanias the Lacedaemonian, son of Cleombrotus, at a later day betrothed to himself, since it was his wish to possess the sovereignty of Hellas. After appointing Megabates general, Artaphrenes sent his army away to Aristagoras.
