LIVIANA

Literary and ancient, Lysistrata is the Latinized form of the Greek Lysistrate and the variation used by the ancient Greek playwright Aristophenes in his comedy of the same name. Set around the Peloponnesian war, the play sees Lysistrata organize the wives on both sides of the battle to deny their husbands sex until a peace treaty is signed.
 
Literally meaning "releasing, loosening the army", it could more figuratively be interpreted as "one who disbands armies".
 
While it could have the possible nicknames Lissy, Star, Lettie, and Lys, for those who want something rare but not this this rare, then Lysandra is a similar option.

Pelleas and Melisande is a play by Maeterlinck, the inspiration for the Debussy opera of the same name. In modern times, Melisande became a princess via the Rankin and Bass film The Flight of Dragons.

The name of the beautiful red-haired character on Game of Thrones is spelled Melisandre.

Nathaniella is a feminine elaboration of Nathaniel, which itself comes from the Hebrew name Netan'el meaning 'gift of God.' This feminine variant emerged as part of the trend of creating feminine counterparts to masculine biblical names by adding feminine suffixes. Nathaniella is quite rare, appealing to parents seeking a distinctive yet traditional-sounding name with clear biblical connections. The name maintains the spiritual significance of its root while offering a graceful, elaborate feminine form. Potential nicknames include Nella, Ella, Thani, or Nate. While uncommon in official records, Nathaniella represents the continuing tradition of adapting ancient names for contemporary use, particularly for parents wanting a name with religious significance and feminine elegance.

Nicolasa is a feminine name of Greek origin, functioning as the feminine form of Nicholas, which means 'victory of the people.' This name is primarily used in Spanish-speaking countries and communities, offering a distinctly feminine alternative to the more common Nicola or Nicole forms found in English-speaking regions. Nicolasa carries a certain traditional elegance while maintaining connections to the widely recognized Nicholas name family. The rhythmic four-syllable pronunciation (nee-koh-LAH-sah) creates a melodious quality. While not among the most popular names internationally, Nicolasa remains in use particularly in Latin American countries and among Hispanic communities worldwide. The name conveys strength and triumph through its meaning, while its flowing sound gives it a graceful feminine quality that appeals to parents seeking a name with both substance and beauty.

Curiously appealing, in a hoop-skirted, wasp-waisted way, Ottoline has recently entered the realm of modern possibility, especially since Sienna Miller chose it as the middle name of her daughter Marlowe.
 Lady Ottoline Morrell was an influential British aristocrat who was a force in the artistic and literary community of her day, patron of such figures as T. S. Eliot and Aldous Huxley.
 The Franco-German Ottolie is an equally intriguing option.

Petronilla is an ancient saint's name that relates to the Roman family name Petronius, thought to mean yokel or woodpecker, though some connect it with Petra or Peter, meaning stone.  With the resurgence of so many ancient Roman names, the elaborate and pretty Petronilla or its French form Petronille seem more usable these days than they have in centuries.

Pomeline

Sounds like a fictional rank of royalty. 

Quintessa

Romancia is an exceptionally rare feminine name that evokes notions of romance and elegance. It appears to be derived from the Latin 'romanicus' or similar roots relating to Rome or the Romance languages. The name carries a distinctly romantic, literary quality with its flowing syllables and soft sounds. Romancia might be considered a more elaborate form of the name Roma or an inventive feminine variation of Roman. Despite its classic linguistic roots, the name has minimal documented usage historically, making it a truly unique choice. For parents seeking a name with a romantic, almost poetic quality, Romancia offers sophistication and distinctiveness while maintaining connections to classical Latin heritage.
