Histories

Aristagoras had no way of fulfilling his promise to Artaphrenes, and he was hard-pressed by demands for the costs of the force. Furthermore he feared what might come of the failure of the army and Megabates' displeasure against him. It was likely, he thought, that his lordship of Miletus [27.3,37.5] (Perseus) Miletus would be taken away from him.

With all these fears in his mind, he began to plan revolt, for it chanced that at that very time there came from Shush [48.333,32.2] (inhabited place), Khuzestan, Iran, AsiaSusa Histiaeus' messenger, the man with the marked head, signifying that Aristagoras should revolt from the king.
