Feminine resistance to masculine sexual approaches is a recurring motif in the so-called «celestinesque genre», in which it almost invariably serves as foreplay for intercourse. This motif evidences an erotisation of violence that, according to a significant portion of early-modern erotic poetry, acts as a stimulant of male desire. However, this aphrodisiac power, apparent in the poetic compositions of the 16th century, is not as evident in the literature of the Middle Ages. As a result, it becomes necessary to explain how this motif reachs Celestina as early as the end of the 15th century. In this paper, I will explore the role that Ovid’s Ars amatoria and chivalric literature could have played in the introduction of such a motif.
