The poetry of Gaius Valerius Catullus was written towards the end of the Roman Republic in the period between 62 and 54 BC.

Latin obscenity is the profane, indecent, or impolite vocabulary of Latin, and its uses. Words deemed obscene were described as obsc(a)ena, or improba. Documented obscenities occurred rarely in classical Latin literature, limited to certain types of writing such as epigrams, but they are commonly used in the graffiti written on the walls of Pompeii and Herculaneum. Among the documents of interest in this area is a letter written by Cicero in 45 BC to a friend called Paetus, in which he alludes to a number of obscene words without actually naming them.
