Vulgar work of Catullus
In the 1st century BCE Roman poet Gaius Valerius Catullus (c. 84 – c. 54 BCE) wrote a poem that was addressed to two critics of his work: another poet Marcus Furius Bibaculus and senator Marcus Aurelius Cotta Maximus Messalinus. The text was so vulgar and obscene that it was not translated from Latin until the 20th century.
