Dioscures
Castor and Pollux aspired to marry the Leucippides ("daughters of the white horse"), Phoebe and Hilaeira, whose father was Leucippus ("white horse"). Both women were already betrothed to cousins of the Dioscuri, the twin brothers Lynceus and Idas of Messenia, sons of Tyndareus's brother Aphareus. Castor and Pollux carried the women off to Sparta wherein each had a son; Phoebe bore Mnesileos to Pollux and Hilaeira bore Anogon to Castor. This began a family feud among the four sons of the brothers Tyndareus and Aphareus.
