Castor and Pollux were two twin brothers from ancient Greek mythology who were considered to be the sons of Zeus, the king of the gods. They were born to a mortal woman named Leda, who was also married to a king named Tyndareus.
Castor and Pollux were quite different from one another. Castor was a great horseman and a skilled fighter, while Pollux was a master of boxing and a champion wrestler. However, despite their differences, the two brothers were inseparable and always looked out for one another.
One day, while they were on a journey, Castor was killed in a battle. As Pollux grieved for his brother, he prayed to Zeus to allow him to share his immortality with Castor so that they could always be together. Zeus was moved by Pollux's devotion to his brother and granted his request. From that point on, Castor and Pollux became known as the Heavenly Twins and were revered as symbols of loyalty and brotherly love.
In ancient times, many people believed that Castor and Pollux appeared in the sky as two bright stars, which were later named after them. These stars are part of the Gemini constellation and can still be seen today. They are also used as a symbol of good luck and protection in many cultures.
