I suppose it was inevitable that Themistocles was ostracised. I saw two of his ostraka in the Agora museum in Athens. Cavafy writes about how Cavafy finds himself in the court of Artaxerxes, Xerxes' son in Persia. It is easy to imagine how Themistocles must be feeling from Cavafy's poem.

THE SATRAPY
What a calamity that you who are made
for beautiful achievements and renowned,
should always be, through your hard fate, denied
occasion and success; that you should always
be hindered by the mean observances,
the pettiness, and indifference.
And how unblest the day when you give in
(when you have lost yourself, and you give in),
and you depart, a wayfarer for Susa,
and come before the monarch Artaxerxes
who welcomes you with favour at his Court,
offering you satrapies and things akin.
And you, despairing, you accept those honours,
those that are not the honours you desire.
Your soul is hungering for other things:
the praises of the Demos and the Sophists, —
the difficult, invaluable “Well done”;
the Agora, the Theatre, the garlands.
These — how should Artaxerxes ever give,
how should you ever find in satrapies;
and what a life will yours be now, without them.
I could have posted my translation, which I prefer, but this one was on Cavafy's website. I have made a few changes to it.
If anyone would like me to post the original Greek of this poem, just ask. :-)
Good luck to the next challenger.
