While, under the presiding genius of Themistocles, Athens was silently laying the foundation of her naval greatness, and gradually increasing in influence and renown, the Persian monarch was not forgetful of the burning of Sardis and the defeat of Marathon.

The armies of a despotic power are often slow to collect, and unwieldy to unite, and Darius wasted three years in despatching emissaries to various cities, and providing transports, horses, and forage for a new invasion.
The vastness of his preparations, though congenial to oriental warfare, was probably proportioned to objects more great than those which appear in the Greek historians.

There is no reason, indeed, to suppose that he cherished the gigantic project afterward entertained by his son--a project no less than that of adding Europe as a province to the empire of the East.
