Xenocles in Wikipedia

Xenocles (Ξενοκλῆς) or Zenocles was an Ancient Greek tragedian. There were two Athenian tragic poets of this name, one the grandfather of the other. No fragments of either are currently known, except for a few words of the elder apparently parodied in Aristophanes' "The Clouds". Aristophanes called the elder Xenocles an execrable poet and was never tired of ridiculing him; describing, along with his father, Carcinus of Agrigentum, three brothers and a member of the third generation (also called Carcinus), "a whole potful of tragic crabs". He also wrote that "Xenocles, who is ugly, makes ugly poetry". In his play The Poet and the Women Aristophanes' chorus claims "Even this audience, I'm sure/Would find the man a crashing bore." which highlights his doubtful views on Xenocles as a writer. However, in 415 BC Xenocles gained the first prize with one of his trilogies when in competition with Euripides. But Aelian accounts for this by saying that "the jury were either intellectually incapable of a proper decision or else they were bribed."
