Wincenty of Kielcza

Wincenty of Kielcza (c. 1200–after 1262) was a Polish Dominican canon, poet, and the first Polish composer known by name. From about 1222 he served as chaplain to Bishop Iwo Odrowąż of Kraków, becoming a Kraków canon in 1257 and prior of the Dominican house at Racibórz in 1258–1260.

For the 1254 translation of Saint Stanislaus's relics he composed the liturgical office Historia gloriosissimi Stanislai, containing the hymn Gaude Mater Polonia, long sung by Polish knights after victory. He also wrote two lives of Saint Stanislaus.
