Ovid, Fasti 3.695:
“Nothing was more pleasing to Venus than this. For that reason, the ancient jokes and obscene songs are sung, and it helps her to have given words to the great god.”

Petronius, Satyricon 85.2.4:
“Whenever mention of the use of beautiful boys was made in that party, I grew so violently pale, and with such severe sorrow I did not wish my ears to be violated by obscene talk, that my mother especially looked upon me as one of the philosophers.”
quotiescumque enim in convivio de usu formosorum mentio facta est, tam vehementer excandui, tam severa tristitia violari aures meas obsceno sermone nolui, ut me mater praecipue tamquam unum ex philosophis intueretur.
