Greek mythology
Terpsichore ('delight in dance') was the daughter of Zeus and Mnemosyne, muse of dance and chorus.
The asteroid Terpsichore is related with the ability to accompany verbal communication through gestures of the hands, arms, body posture, and in general, with movements of the whole body.
Stana Katic, actress of the TV series "Absentia (2017), has Terpsichore in Scorpio (11th Moon-Node House), in conjunction with Uranus.
