Blue Corn Woman, called 'near to Summer,' is one of the two primordial Corn Mothers who existed with the people in the underworld at Sipofene beneath Sandy Place Lake before the emergence. She is the mother of the Summer moiety, the warm half of the dual Tewa social and cosmological order, and stands opposite White Corn Maiden, mother of the Winter people. From her descend the Summer chief and the Summer division of the pueblo, and her presence is carried in the feathered mother-corn ear that is central to Tewa ritual. Sources describe the two mothers together as the origin of all Tewa, without a recorded father, expressing the matrilineal generative principle at the root of the moiety system.
