The constellation of Pisces is based on a tale from Greek mythology and involves three main characters. Firstly we have Typhon, son of the Earth Goddess Gaia. Typhon was a gigantic monster who was as tall and wide as the mountains with the head of a hundred dragons. Typhon could breathe fire from his many eyes and was capable of destruction on a massive scale, he was the most fierce and the most feared monster in Greek mythology.
One day Gaia ordered Typhon to destroy Olympus, home of the Gods. On his approach to Olympus the Gods began to flee including the other two characters in the tale, Aphrodite the Goddess of Beauty and her son Eros, the God of Love. After reaching a river bank Aphrodite and Eros tie a rope to each other and turn themselves into fish before leaping into the water, the rope prevented them from becoming separated as they eventually swam to safety. To celebrate the event the figures of two fish were later placed amongst the stars.
