In Greek mythology Leda was the wife of the king of Sparta. Zeus raped and impregnated her in the form of a swan. This led to the Trojan War indirectly. It's a great but long story! "Where the slow river meets the tide, a red swan lifts red wings and darker beak, and underneath the purple down of his soft breast uncurls his coral feet... Ah kingly kiss— no more regret nor old deep memories to mar the bliss... ~Leda, by H.D.
