The Shu-Tefnut twins are a pair of deities in ancient Egyptian mythology, representing the concepts of air and moisture, respectively. Shu (also spelled Shu) is the god of air and dryness, while Tefnut (also spelled Tefnut) is the goddess of moisture and dew. Together, they are considered the children of the creator god Atum and are integral to the creation myth of Egypt. The twins are also associated with the concept of balance and harmony in the universe. In Hebrew, Shu is translated as שו and Tefnut as טפנת. In ancient Egyptian, their names are transliterated as šw and tfnt, respectively. The Shu-Tefnut twins are often depicted as lion-headed deities, symbolizing their roles in maintaining cosmic order and protecting the sun god Ra.
