[1] Vitruvius goes on to state that Zoilus also may have been stoned at Chios or thrown alive upon a funeral pyre at Smyrna.

Either way Vitruvius felt it was just as well since he deserved to be dead for slandering an author who could not defend himself.

Zoilus appears to have been at one time a follower of Isocrates, but subsequently a pupil of Polycrates, whom he heard at Athens, where he was a teacher of rhetoric.

Zoilus also wrote responses to works by Isocrates and Plato, who had attacked the style of Lysias of which he approved.

[1] However, the Homeric Question led to his name becoming a byword for harsh and malignant criticism: in antiquity he gained the name "Homeromastix", "scourge of Homer"; in the modern period, Cervantes calls Zoilus a "slanderer" in the preface to Don Quixote and there is also a (now disused) proverb, "Every poet has his Zoilus."
