Leda (Λήδα) is from the Lycian lada (woman, wife). **Spartan queen, mother of Helen of Troy and the Dioscuri (Castor and Pollux)** — **Zeus came to her in the form of a swan** and she laid two eggs, from which the four children were born. **One of the most painted subjects in Western art** — by Leonardo, Michelangelo, Correggio, Tintoretto, Boucher. **Yeats's *Leda and the Swan* (1924)** is among the most-anthologized poems of the 20th century.
Featured in Euripides's *Helen* and Apollodorus's *Library*.
Leda reduces to nine — the number of Helen's mother.
