The ancient Sumerians had a goddess of menstruation - Apparently.
The Sumerians, who lived in Mesopotamia around 4500 years ago, worshipped a goddess named Ninsun, who was associated with fertility and childbirth. However, they also had a separate goddess named Kubau, who was specifically revered as the patron of women's menstrual cycles. This unusual reverence for menstruation is documented in the Sumerian king list, which dates back to around 2100 BC. This fact highlights the Sumerians' unique cultural and spiritual practices surrounding women's health and fertility.
