A design inspired by the Greek myth of Leda.
The legend tells she was a young beautiful woman who one day was relaxing on the banks of a river, when she was seduced by Zeus disguised in the shape of a swan. From their union, two eggs were born.
One of the eggs held the beutiful Helen and Pollux, the second egg  held Castor and Clytemnestra.
Several versions are known, but Castor and Pollux are always mentioned, the two Dioscuri, twin God brothers children of Zeus.
Castor, horses tamer, and Pollux, talented in boxing, protectors of sailors.
