Art has a love of chance, and chance for art.
-Agathon, Fragment 4. He means to say that the two are inseparable from one another. 
Agathon (5th c. BC) was a Greek Tragic Poet (and apparently super smexy, according to ancient sources) whose poems and plays do not survive today. Some of his work is referenced in Aristotle and he is depicted in works of Plato and Aristophanes, the former seeming to have some kind of artistic crush oh him. He was a mainstay at the court of Macedon and was also broskis with Euripides.
