Alcibiades (24.5-25.1)

And thus it was that Tissaphernes, though otherwise the most ardent of the Persians in his hatred of the Hellenes, so completely surrendered to the flatteries of Alcibiades as to outdo him in reciprocal flatteries. Indeed, the most beautiful park he had, both for its refreshing waters and grateful lawns, with resorts and retreats decked out in regal and extravagant fashion, he named Alcibiades; everyone always called it by that name.

Alcibiades now abandoned the cause of the Spartans, since he distrusted them and feared Agis, and began to malign and slander them to Tissaphernes. He advised him not to aid them very generously, and yet not to put down the Athenians completely, but rather by niggardly assistance to straiten and gradually wear out both, and so make them easy victims for the King when they had weakened and exhausted each other.
