Greek Mythology Notes

Thoosa

nymph
Θόοσα
sea, swiftness

Sea nymph and mother of the Cyclops Polyphemus.

The Myth

Thoosa was a daughter of the sea god Phorcys, and her name means "the swift one." She bore Polyphemus to Poseidon, making the famous one-eyed giant both a child of the sea and of the earth. When Odysseus blinded Polyphemus, it was Thoosa's relationship with Poseidon that explained the sea god's relentless persecution of Odysseus across the Mediterranean. Though mentioned only briefly in Homer, Thoosa is the hidden link that connects the Cyclops episode to Odysseus's decade of wandering.

Fun Fact

Without Thoosa, there is no wrath of Poseidon — she is arguably the most consequential minor character in the entire Odyssey.
