Dioskouroi

The Dioskouroi, meaning "sons of Zeus," were twin brothers in Greek mythology, Castor and Polydeuces (Pollux). They were born from the same mother, Leda, but had different fathers. Castor was the mortal son of Leda and her husband Tyndareus, while Polydeuces was the immortal son of Leda and Zeus, who visited her in the form of a swan. This dual parentage is often depicted as Leda laying eggs from which the twins hatched.

The Dioskouroi were renowned for their inseparable bond and shared adventures. They were skilled horsemen, boxers, and sailors, and participated in various famous myths. Most notably, they were Argonauts, accompanying Jason on his quest for the Golden Fleece. They also played a role in the Calydonian Boar Hunt.

Their close relationship extended beyond life. When Castor was killed in battle, Polydeuces was so grief-stricken that he begged Zeus to allow him to share his immortality with his brother. Zeus granted this wish, and the twins were placed among the stars as the constellation Gemini. They are often depicted as horsemen, symbolizing their equestrian skills and their eternal companionship. Their cult was widespread in ancient Greece, and they were invoked for protection, especially by sailors and warriors.
