In Greek mythology, Tethys (Ancient Greek: Τηθύς, Tēthýs) was a Titan daughter of Uranus and Gaia, a sister and wife of the Titan Oceanus, and the mother of the river gods and the Oceanids. Although Tethys had no active role in Greek mythology and no established cults, she was depicted in mosaics decorating baths, pools, and triclinia in the Greek East, particularly in Antioch and its suburbs, either alone or with Oceanus.
