What is the ancient Greek legend about Ganymede becoming Aquarius?

Nemesis is the Prince of Troy. He is handsome, especially his whole body shines with golden light, which is very eye-catching. The young Ganymede is very playful and often slips out of the palace to play by the sea. Zeus turned into an eagle, fell behind him when traveling in Nemesis, grabbed Nemesis's waist with his harmless claws and took him to Mount Olympus. Here, Nemesis has nowhere to go but to accept the work of pouring wine for the gods, thus obtaining an immortal priesthood. He was lifted into the air in the image of a water bottle pouring water and became a water bottle.
