Mokosz is the Polishish goddess of home and hearth, and female occupations such as spinning, weaving and fate. She is called Mokusa also in Polish folklore, and at night, women would leave strands of fleece beside the stove in her honor. She is seen as the goddess of fertility, bounty, as well as occult knowledge and divination. Her sacred day is Friday; and her feast day falls between October 25th and November 1st. One reference fixes this day to October 28th. She was offered vegetables, which was the focal point of the feast day. It was said that women who made satisfactory offerings would be helped with their laundry, associating her as a water goddess. This is illustrated by the fact that rainfall is sometimes called "Mokosz's milk." In Christian times she became conflagrated with the Virgin Mary and Saint Paraskeva. She is sovereign over the Domowije and the patroness of midwifery. In one myth, she is the wife of Piorun, and was represented as a woman with a large head, long arms and unkept hair. In another myth she is wife of Swarog, which created a marriage of heaven and Earth.
