The Symposium

Xenophon of Athens was a Greek poet, historian, soldier and philosopher, living at a time of momentous events in Ancient Greek history. He wrote about the philosophy of Socrates, the Peloponnesian War between Athens and Sparta, and the Persian expedition that formed the basis of his most famous work, "Anabasis." In addition to his own works, he influenced the account of the Peloponnesian War written by the famous Greek historian Thucydides.
Although he was recognized as a great writer and poet in his lifetime, Xenophon's involvement with Spartan politics and fighting led to his exile from Athens, and his association with Socrates probably did not help. His short treatise on Sparta's government is considered one of the first examples of political philosophy.
