Greek mythology

Atemis was the virgin goddess of hunt, wild animals and uncultivated lands. She was associated with the Moon. She preferred free living in the countryside and forests, to that of cities.

On one occasion, Zeus --disguised as Artemis-- seduced one of her companions, a beautiful princess named Callisto. After a few months, when she went to take a bath with Artemis, she discovered that she was pregnant. Very anger, she turned Callisto into a bear to be hunted. On another occasion, Actaeus of Thebes, faithful follower of Artemis and virgin like her, had the bad luck to clash with the goddess in one of his hunts while she was bathing naked. Artemis, relentless, turned him into a deer who was killed by his own hunting dogs.

This mythology describes the subjective experience of being exposed to the appearance of hunters or predators, like at the beginning of the movie "The Bourne Supremacy" (2004).


(105) Artemis is related to the ability to detect environmental signals that are out of the usual (3:11 resonance with the Earth-Moon system).
