This paper aims to contribute to the study of phraseology, more specifically, of Latin phraseology through the analysis of phraseological units that appear in the best known episode of Petronious’ Satyricon: Trimalchio’s Feast (chapters 27-78) and their different translations into Spanish. The units analysed are phrases that refer to the expression of contempt and the proposed translations. A preference of expressions with names of coins, parts of the body, bodily functions and metaphors from the farming world is observed.
