This paper aims at searching the ties between authorship and money in the Roman times, from Plautus to the Antonines. The first part is about the authors who could earn some money or gain some financial advantages thanks to their literary production : first the authors of plays who sold them to an actor or a magistrate for a festival, then the poets in the shadow of a powerful family like Ennius. Martial under the Flavians is an interesting example of an author between two mental representations, wishing loudly to earn some money but hoping for glory as the ultimate gain, which allows to present another conception of authorship in ancient Rome. Many writers did not care about the money or financial gain, and then about copyright : writing was a social activity, a way to celebrate publicly a friendship, or a political device for propaganda.
