Thetis. One of the daughters of Nereus and Doris, was a marine divinity, and dwelt - like her sisters, the Nereids -in the depths of the sea, with her father Nereus. She there received Dionysus (Bacchus) on his flight from Lycurgus, and the god in his gratitude presented her with a golden urn. When Vulcan was thrown down from heaven he was likewise received by Thetis. Thetis rejected the offers of Zeus, because she had been brought up by Hera, and the god, to revenge himself, decreed that she should marry a mortal.
