Since 1993 and the ground-breaking thesis of French historian Nicole Boëls-Janssen, it is rare to find publications that discuss the powers of female bodies, and in particular of menstrual blood in ancient Rome. 1 There is no mention of this blood in any of our pre-Imperial sources, perhaps due to the limited range of evidence rather than a lack of interest from the Romans. However, each and every Latin author examined in this article has acknowledged their debts to foreign influences, especially Hellenistic philosophy and medicine which started to flourish as early as the 5 th century BC. Even though these works contain numerous allusions to Greco-Egyptian practices, it does not mean similar ones were unknown or employed elsewhere in the Roman world at the same time (Aubert 1989, p. 422). As such, this paper analyses how menstrual blood was understood by the Romans, potentially as early as the 3 rd century BC. 2 Unfortunately, Boëls-Janssen's thesis is also one of the very few works that have discussed both the dangerous and beneficial properties of this blood. In her Introduction dedicated to women's apotropaic powers, she explains how "certaines parties du corps féminin semblent avoir été l'objet de précautions ou de superstitions particulières" (1993, p. 4). Indeed, the female nature and its unique powers were associated with several bodily fluids such as urine and saliva, but also the intriguing blood that flowed out of women's bodies every month. 3 Following in her footsteps, this paper aims to examine the social representations falling upon menstrual blood, as well as its uses symbolizing one of the most powerful feminine insignia in Ancient Rome.
2A more recent number of publications have investigated the role of menstrual blood, including most notably Jack Lennon's article (2010) who subjected this topic to an anthropological enquiry supported by Mary Douglas' (1966) key concepts. Lennon's aim was to demonstrate that menstrual blood was a source of danger and power, an idea further argued in his monograph (2014, p. 56 and 84-85). This paper also builds upon other publications that have qualified Douglas' main theories, and in particular Menstrual Blood: Uses, Values, and Controls in Ancient Rome Cahiers « Mondes anciens », 16 | 2022
