Cynthia comes from Greek Kynthia, an epithet of the goddess Artemis, meaning 'of Kynthos', the mountain on the island of Delos where she and her brother Apollo were said to have been born. Roman poets used Cynthia as a name for the moon goddess and for the moon itself, and English poets of the 16th and 17th centuries applied it to Queen Elizabeth I. It became a common American given name in the mid-20th century.
