In Aztec mythology, Cihuacoatl was one of a number of motherhood and fertility goddesses. Cihuacoatl was especially associated with midwives, and with the sweatbaths where midwives practiced. She is paired with Quilaztli and was considered a protectress of the Chalmeca people and patroness of the city of Culhuacan. She helped Quetzalcoatl create the current race of humanity by grinding up bones from the previous ages, and mixing it with his blood. She is often shown as a fierce skull-faced old woman carrying the spears and shield of a warrior. Childbirth was sometimes compared to warfare and the women who died in childbirth were honored as fallen warriors.
