The constellation of Capricorn is a sea god, with the head and half the body of a goat, and the tail of a fish. When Zeus became the lord of the universe, he did not forget his goat-mother, Amaltheia, who had nursed him so lovingly. He took one of her horns and turned it into the horn of plenty, which is always filled, and set her image among the rest of the stars as the constellation of Capricorn.
The twins represented in Gemini mythology are Castor and Pollux. They share the same mother, Leda, but have different fathers – Tyndarus and Zeus. The twins were young, handsome, and adventurous. They took part in many adventures together and were well known for their livelihood and curiosity. Castor was a renowned horseman, while Pollux was known for his great strength.
