Apparently, Catullus the Late Republic Roman poet didn't take too kindly to criticism. Here is poem #16 in Latin:
pedicabo ego uos et irrumabo,
Aureli pathice et cinaede Furi,
qui me ex uersiculis meis putastis,
quod sunt molliculi, parem pudicum.
nam castum esse decet pium poetam
ipsum, uersiculos nihil necesse est;
qui tum denique habent salem ac leporem,
si sunt mollicui ac parum pudici,
et quod pruriat incitare possunt,
non dico pueris, sed his pilosis
qui duros nequeunt mouere lumbos.
uos, quod milia multa basiorum
legistis, male me marem putatis?
pedicabo ego uos et irrumabo
I will bugger you and fuck your mouths,
Aurelius the pansy and Furius the pervert,
for you thought from the evidence of my little poems
that I was not modest enough because they are slightly unmanly.
For the holy poet ought to be pure
himself, but his little poems need not be like that;
they do at least have wit and charm
even if they are slightly unmanly and insufficiently modest
and can arouse something to give people the urge -
I do not mean boys but these hairy men
who cannot shift their stiff loins.
You, because you read many thousands of
kisses, do you think me lacking in manliness?
I shall bugger you and fuck your mouths.
Oh, those crazy Romans!
