"Oedipus Rex" is a great play, so is "Antigone".
If the three men I have proposed are studied, may I suggest that we study them in chronological order:
1. Themistokles 524-459 BC. Populist from humble beginnings. Clawed his way to fame. Moving force at Salamis in routing the Persian fleet.
2. Pericles 493-429 BC. Aristocrat who, along with his family, would probably have been evacuated from Athens at the time of the Battle of Salamis. He would have been about 13. Politically active from c.461 BC.
3. Alcibiades died c.404 BC. The Greek Bad Boy. Makes interesting reading. Aristocratic, said to be descended from Ajax. Adopted by Pericles.
"In him nature seems to have tried what she could do; for it is agreed among all who have written concerning him, that no one was ever more remarkable than he, either for vices or virtues. Born in a most distinguished city, of a very high family, and by far the most handsome of all the men. of his age, he was qualified for any occupation, and abounded in practical intelligence. He was eminent as a commander by sea and land; he was eloquent, so as to produce the greatest effect by his speeches; for such indeed was the persuasiveness of his looks and language, that in oratory no one was a match for him.
