etymonline
Pollux
twin brother of Castor (q.v.), hence also the name of the beta star of Gemini (though slightly brighter than Castor), 1520s, from Latin, from Greek Polydeukēs, literally "very sweet," or "much sweet wine," from polys "much" (from PIE root *pele- (1) "to fill") + deukēs "sweet" (prom PIE *dleuk-; see glucose). The contraction of the name in Latin is perhaps via Etruscan [Klein].
