Τηθύς, in Greek mythology, is a primordial sea goddess and one of the Titans. She is often associated with the nourishing aspects of the sea and is considered the mother of many sea deities. Tηθύς is the daughter of Uranus (the sky) and Gaia (the earth), symbolizing the connection between the earth and the ocean. As the wife of Oceanus, another Titan, Τηθύς is the mother of the Oceanids, who are nymphs of the ocean. She represents the life-giving and nurturing qualities of water, playing a vital role in the mythological understanding of the natural world.
