quote: ''
summary: The passage describes Thetis as a beautiful sea-divinity associated with
Nereus or Poseidon, sought by Zeus and Poseidon but married to Peleus after a
prophecy that her son would surpass his father. It recounts her shape-shifting
during Peleus' courtship, her divine wedding attended by the gods except Eris,
her influence on Zeus for Achilles, and her transformation of Ceyx and Halcyone
into paired kingfishers connected with calm 'halcyon-days.' The passage then describes
Thaumas, Phorcys, and Ceto as offspring of Pontus and personifications of sea
phenomena, with Thaumas linked to the mirror-like sea, Electra to amber tears,
and Phorcys and Ceto to oceanic terrors and monstrous offspring.
