Meaning and Epithets

Tethys’ name, which came from the Greek word “têthê”, translates into words such as “Grandmother” and “nurse”. Similarly, she was called the “Nurse of Hera” after she and her husband Oceanus took in Hera for safe keeping at the beginning of the clash between the Titans and the Olympians.

Titaness Tethys was born to the Earth goddess Gaia and the sky god Uranus. According to Hesiod, Tethys was a member of the first generation of Titans that included Cronus, Oceanus, Iapetus, Themis, Phoebe, Rhea, Hyperion, Coeus, Crius, Mnemosyn and Theia.

The two other categories of siblings of the Greek Titans were the Cyclopes and the Hecantoncheires, both of who were hideous monstrosities and creatures, with some of them having up to hundred hands.

As it was so typical of ancient Greek deities to marry from within the family, Tethys took her brother Oceanus for a husband. Long before there was the Olympian Poseidon there was Oceanus, the embodiment of the oceans of the world. It was believed that Oceanus was the deity that encircled the entire world.

With her husband Oceanus, Tethys bore numerous children, including: the Oceanids (a group of 3,000 water-nymphs such as Doris, Eurynome, Metis, Clymene and numerous others); Ptotamoi (river gods such as Alpheus, Achelous, Scamander and many others); Nephelai (clouds).

According to Hesiod, Tethys gave birth to a whopping three thousand river gods (i.e. Ptotamoi)

There are quite few representations and depictions of Tethys from the ancient Greek era. In those depictions of Tethys, the Titaness was shown alongside her husband Oceanus, Erotes (Loves) and Eileithyia, the goddess of childbirth. Her association with Eileithyia reinforces her epithet as the “Mother of the gods”.

The ancient Greeks and Romans typically depicted Tethys as a simple woman who sometimes had horns or wings coming out of her eye brow. Some mosaic paintings show her with fish and other sea creatures on top of her head. On her shoulder is often a fierce sea-serpent. In most cases, she is seen surrounded by a number of winged Erotes (love).

Tethys was the one who turned Aesacus into a diving bird. Aesacus was the son of the famous King Priam of Troy. Aesacus’ transformation came when he tried to commit suicide by leaping off a cliff.

According to some accounts, Oceanus and Tethys were the first deities that appeared, i.e. the parents of the Greek Titans. Homer described the two titans as the parents of all the Greek gods.  The 7th century BCE Greek philosopher and poet Epimenides of Cnossos had similar ideas. According to Epimenides, Tethys and Oceanus emerged from Tartarus, who in turn emerged from Night and Aer, the first two beings at the beginning of time.

Some historians and mythologists have drawn parallels to the relationship between Tethys and Oceanus and the relationship between Babylonian deities Apsu and Tiamat. In both cases, the two couples were described to have an estranged relationship that was seen as the female and male waters.
