"Worldwide, the amount of ethnographic and textual work on menstruation is disproportionately larger than the amount of archaeological work on the subject. While researching for my project at Deir el-Medina, I found only four published studies that attempt to identify menstruation in the archaeological record: Claassen 2011, Faust and Katz 2017, Bengtson 2017, and Crown 1985. I was not surprised by this result, as menstruation is still taboo in the western world, but the result also stems from the lack of visibility of menstruation in the archaeological record. Patricia Galloway’s “Where have all the menstrual huts gone?” rightfully points out that this is unsubstantiated assumption, one not supported by the ethnographic and textual descriptions of these practices."
