The article contains an edition of an autobiographical poem by Anna Ludwika Radziwillowa de domo Mycielska (1729-1771) preceded by a literary historical introduction. The piece, unpublished so far, was restored as based on two handwritten copies. Anna Ludwika Mycielska married in 1744 Leon Michal Radziwill, with which she became close to the court of Franciszka Urszula Radziwillowa, a poetess and an animator of theatre life in Nesvish Castle. It is likely that Anna Ludwika started composing poems under Franciszka Urszula's influence. Sickly Leon Michal passes away in the year 1751. After his death the young widow, uncertain about her destiny and concerned about her children's sicknesses, composed a lamentatory verse in which she complains about the suffering after the death of her father and husband, the latter's long sickness and adequately unexplained defamation. Discouraged to people, she directs her complaint to God, combining an autobiographical statement with the phraseology typical of prayer literature. Anna Ludwika Radziwillowa's poem is an example of an 18th century Polish female poetry which deserves extraction from manuscripts and description.
