Thucydides, History of the Peloponnesian War:

What are the major themes of Pericles’ Funeral Oration in Book Two and explain how they play throughout the text? Does Thucydides maintain them consistently throughout? If so or if not, explain. How does our understanding of this speech help us in understanding the text as a whole?
How does the Melian Dialogue (Book Five) fit into Thucydides’ narrative and how does it help us to understand questions of justice, law and morality in the text? Why do you think he adopts a “dialogue” presentation?
In Books VI and VII of his History of the Peloponnesian War, Thucydides relies on the principles of tragedy to relate to his readers the destruction of the Athenian army in Sicily. What are those elements and how do they work?
