Greek mythology
Otrera was the first Amazonian queen and founder of the Amazonian nation. She was mother of four daughters: Hippolyte, Melanipa, Antiope and Penthesilea.
The ninth labor of Heracles was to obtain the Girdle of Hippolyte (sister of Antiope), which his father (Ares, the god of war) had given to her. Heracles kidnapped Antiope and demanded the Girdle of Hippolyte as exchange.
(385571) Otrera is related with the ability to imagine possible futures, like in the practice of tarot, I Ching or astrology.
Unlike the sequential progression of chess players, (385571) Otrera jumps directly into a future position, visualizing it in depth with all kinds of details, just like premonitory dreams or the visions of the future in the video game "Prince of Persia - Sands of Time" (PS2, 2003), or the progressions towards future lives under hypnosis described in the book "Same Soul, Many Bodies" (Brian Weiss, 2004).
