Esther (HWV 50) is an oratorio by George Frideric Handel.

 He lived in Paris.
 Two of his poems appeared in the third and final volume of "Le Parnasse contemporain" (1876).
 His poetry has been set as songs by composers including Fauré, Chaminade, Pierné and Bizet.
 He was more well known as a librettist and translator for operas and oratorios.
 He wrote the libretto for César Franck's opera Hulda, set in 11th-century Norway, and based on the play "Lame Hulda" (1858) by Norwegian writer Bjørnstjerne Bjørnson.

Federico Romero Saráchaga (11 November 1886 – 30 June 1976) was a Spanish poet and essayist.
 He is particularly known as a writer of libretti, primarily for zarzuelas. Although he was born in Oviedo and lived at times in both Zaragoza and Madrid, he considered himself a son of Spain's La Mancha region, where his family had lived from the early 20th century in the small town of La Solana (Ciudad Real).
 The zarzuela "La rosa del azafrán", composed by Jacinto Guerrero to a libretto by Romero, is considered emblematic of the region.
Farnace is an 18th-century Italian opera in 3 acts by the Czech composer Josef Mysliveček.
 It was composed to a libretto by the Italian poet Antonio Maria Lucchini that is best known from a setting by Antonio Vivaldi first produced at the Teatro Sant'Angelo in Venice for the carnival operatic season of 1727.
 For a performance in the 1760s, it would only be expected that a libretto of such age would be abbreviated and altered to suit contemporary operatic taste; this libretto was unusually old, even older than all but one of the librettos by Metastasio that continued by be set in the 1760s.
 The cuts and changes in the text made for the 1767 performance of Mysliveček's opera are not attributable.
 Indeed, they are quite extensive; not a single one of Lucchini's original aria texts was re-set by Mysliveček.
Esther Hallam Meynell (née Moorhouse) (1878 in Leeds – 4 February 1955 in Brighton, Sussex), was an English author.
 She is best known for her "The Little Chronicle of Magdalena Bach", a fictional autobiography of Anna Magdalena Bach, the wife of composer Johann Sebastian Bach, and "Nelson’s Lady Hamilton", a book about the life of Emma, Lady Hamilton, mistress of Lord Nelson.
 There are also many books by her about Sussex, where she lived.
 On the other hand, her "Time's Door" belongs to the genre of science fiction due to its theme of time travel.
 Meynell was the niece by marriage of the poet and suffragette Alice Meynell.
Esther Nirina, née Esther Ranirinaharitafika (1932–2004), was a Malagasy poet.

 Her volume of poetry "Simple voyelle" was awarded the ADELF Grand Prix Littérature de Madagascar.
L'Olimpiade is an 18th-century Italian opera in 3 acts by the Czech composer Josef Mysliveček.
 It was composed to a libretto by the Italian poet Metastasio that was first performed in 1733.
 For a performance in the 1770s, it would only be expected that a libretto of such age would be abbreviated and altered to suit contemporary operatic taste; some of the original aria texts would be omitted or substituted, and the remaining aria texts would be set more expansively.
 In this case, only 14 of the original 18 aria texts of Metastasio were newly set to music.
 The cuts and changes in the text made for the 1778 performance of Mysliveček's opera are not attributable.
