The tradition that Diogenes of Sinope wrote tragedies is recorded in Diogenes Laertius 2, 80. His evidence together with that of Philodemus (de stoic. 14,29) offers the list of titles of these tragedies. It is not known when these tragedies were performed. The date range for performance offered here is based on the time when Diogenes came to live in Athens and Corinth (he was exiled from Sinope shortly after 362 BC) up until his death (324/321 BC). The place of performance is not certain, here it has been assumed that the plays were produced in Athens. For Diogenes of Sinope, see TrGF1, 88 Diogenes Sinopensis, p.253-8.
