Ancient Greek literature
Seven works of Sophocles have survived, the most acclaimed of which are the three Theban plays, which center around the story of Oedipus and his offspring. The Theban Trilogy consists of "Oedipus the King", "Oedipus at Colonus", and "Antigone". Although the plays are often called a "trilogy," they were actually written many years apart. "Antigone", the last of the three plays sequentially, was actually first to be written, having been composed in 441 BC, towards the beginning of Sophocles's career. "Oedipus the King", the most famous of the three, was written around 429 BC at the midpoint of Sophocles's career. "Oedipus at Colonus", the second of the three plays chronologically, was actually Sophocles's last play and was performed in 401 BC, after Sophocles's death.
Cynicism (philosophy)
The story of Cynicism traditionally begins with Antisthenes (c. 445–365 BC), who was an older contemporary of Plato and a pupil of Socrates. About 25 years his junior, Antisthenes was one of the most important of Socrates' disciples. Although later classical authors had little doubt about labelling him as the founder of Cynicism, his philosophical views seem to be more complex than the later simplicities of pure Cynicism. In the list of works ascribed to Antisthenes by Diogenes Laërtius, writings on language, dialogue and literature far outnumber those on ethics or politics, although they may reflect how his philosophical interests changed with time. It is certainly true that Antisthenes preached a life of poverty:
I have enough to eat till my hunger is stayed, to drink till my thirst is sated; to clothe myself as well; and out of doors not [even] Callias there, with all his riches, is more safe than I from shivering; and when I find myself indoors, what warmer shirting do I need than my bare walls?
