"Archaeologically, understanding cultural behaviors surrounding menstruation is important because it can provide glimpses into gender relations and gender roles that allow us to understand the social structuring of past societies. However, it is equally important that menstruation be studied in order to personify and connect to the people of the past. As a teenager, I felt removed from the great women of history due to the elimination of menstruation from their stories. This removal is discussed often in literary circles, but it also needs to be tackled in archaeology. Menstruation is a biological continuity that has always occurred to half of the human population and there needs to be a cultural history that is representative of this reality."
