Very little is known about Eupolis' life. His father was named Sosipolis. There are few sources on when he first appeared on the stage. A short history of Greek Comedy, written by an anonymous writer of antiquity, reported that Eupolis first produced a play in the year when Apollodorus was the
Eponymous archon, which would be 430/429 BC. The same source claims
Phrynichus also had his debut that year. However, the
Chronicon of
Eusebius of Caesarea places Eupolis' debut in 428–27 BC and adds that
Aristophanes also produced a play that year. This is the version preserved in the Latin translation by
Jerome. But the Armenian translation places the event in 427/426 BC.
Cyril of Alexandria placed the debut of Eupolis at some point between 428 and 424 BC, and placed the debuts of Aristophanes and
Plato the comic poet during that same period.
George Syncellus gives the same dates, but merely states that Eupolis and Aristophanes were becoming prominent, not when they had their debuts. Syncellus also includes
Sophocles. Sophocles had actually become the pre-eminent playwright in Athens 456 BC, around when
Aeschylus died. Based on the primary sources above, modern historians conclude that Eupolis had his debut as a playwright during the 420s BC, probably in 429 BC. His first production was probably at the
Lenaia, the lesser theatrical festival of his time. The Lenaia are thought to have allowed novices to compete, so they could prove themselves before presenting plays at the
Dionysia festival. His first known play was either
Prospaltioi or
Heilotes. Surviving fragments from the
Prospaltioi include allusions to, and near-quotations of,
Sophocles'
Antigone (442 BC). Scholars are convinced the play targeted
Pericles, due to a famous reference to
Aspasia. This makes it likely that Pericles, who died in 429 BC, was still alive when Eupolis was working on the text. The
Suda claims Eupolis was only 17 years old when he started his career. (This would place his birth around 447/446 BC.) Sources also claim Aristophanes and
Menander were adolescents (
epheboi) at the start of their own careers. This suggests a tradition concerning the precociousness of poets. Although he was at first on good terms with Aristophanes, their relationship subsequently became strained, and they accused each other, in most virulent terms, of imitation and
plagiarism. In the
parabasis of his play
The Clouds, Aristophanes publicly accused Eupolis' play
Maricas of being a copy of fellow comic
Phrynichus and his own
Knights: Eupolis, indeed, first of all craftily introduced his
Maricas, / having basely, base fellow, spoiled by altering my play of the
Knights, / having added to it, for the sake of the cordax, a drunken old woman, whom / Phrynichus long ago poetized, whom the whale was for devouring. —(Chorus [leader], in
The Clouds, line 553–556, transl. William James Hickie, 1871) ==Works==
