Andromeda chained to a rock, depicted in the Uranographia of Johann Bode (1801). Hydra as the largest of the 88 constellations, winds a quarter of the way around the sky its head being found south of the constellation Cancer and the end of its tail found between Libra and Centaurus. As the offspring
of Typhon and the half-woman, half-serpent called Echidna we have the connection with water that this Atu requires. The waters of a raging flood
(Typhon) are destructive (dare we say due to the crabby quality of Cancer) as the bow of the Centaur directs its energy. This seems to indicate the free-flowing vaginal juices of the woman brought on from ecstatic stimulation and then directed by the exploding male ejaculant. Hydra winds across the pages of John Flamsteed‟s Atlas Coelestis. On
its back are Corvus and Crater, associated with it in legend.
