Unsorted sources I have yet to properly investigate:

• “We didn't know whether to laugh or cry: the case of Karkinos I of Athens,” in D. Harvey and J. Wilkins (eds.), The Rivals of Aristophanes (London)
• A Dictionary of Greek and Roman biography and mythology. By various writers. Ed. by William Smith.
• Rothwell, Kenneth S. "Was Carcinus I a tragic playwright?." Classical Philology (1994): 241-245.

• Believed to have been born c. 480 BCE.^[1]
• "probably best known for the dance his sons performed at the end of the Vespae" ("Was Carcinus I A Tragic Playwright?")
• Likely the same Carcinus who served as general alongside Proteas and Socrates in 431 BCE, during the Peloponnesian War (Thucydides 2.23.2, Diodorus 12.42.7).
• Member of the priest class and "active in public affairs".
• Erroneously referred to as Carcinus of Agrigentum; this is likely a result of confusion between him and his grandson. The latter is more likely to have had intercourse with Agrigentum, given his frequent visits to Sicily.
• May have won first prize at the Dionysia in 447/6 BCE, though this is contested because the only evidence that can be found is a listing with the first two characters of his name.
