Artemis (Greek goddess).
"In ancient art, Cynthia is often depicted as the moon-goddess Artemis holding a bow and arrow."
Borrowed from Latin Cynthia, from Ancient Greek Κυνθία (Kunthía), feminine of Κύνθιος (Kúnthios, "Cynthian (of or pertaining to Mount Cynthus, a mountain of Delos, celebrated as the birthplace of Apollo and Artemis)").
