Placide Cappeau was the author of "O Holy Night" which was set to music by what French composer and music critic
Adolphe Adam Adolphe Charles Adam (] ; 24 July 1803 – 3 May 1856) was a French composer and music critic. A prolific composer of operas and ballets, he is best known today for his ballets "Giselle" (1841) and "Le corsaire" (1856, his last work), his operas "Le postillon de Lonjumeau" (1836), "Le toréador" (1849) and "Si j'étais roi" (1852)
Sebastian Grabowiecki Sebastian Grabowiecki (c. 1543 – 1607) was a Polish Catholic priest and poet. He was the author of "Setnik rymów duchownych" and "Setnik rymów duchownych wtóry" ("Spiritual Rhymes" parts 1 and 2). His work, focused entirely on religious themes (like George Herbert's), was strongly influenced by Italian poetry, especially by "Rime Spirituali" by Gabriele Fiamma. One of the founding fathers of Polish lyric poetry, Grabowiecki was one of the first poets to write sonnets in Polish. Thus he holds a position comparable to Thomas Wyatt, Henry Howard, Earl of Surrey and Portuguese poet Francisco de Sá de Miranda, who introduced the sonnet into their native literatures. He also wrote the first Polish poem in ottava rima, and was an early adopter of the Sapphic stanza in Polish poetry. His best-known poem is a sonnet (based on one of Fiamma's) similar to Philip Sidney's Sonnet 89 from "Astrophel and Stella" ("Now that of absence the most irksome night"), with the use of epistrophe (repetition of end-words) instead of rhyme.
