[3] Sebastian z Felsztyna was probably born in Felsztyn, Kingdom of Poland (now Skelivka, Ukraine).
In 1507 he entered Kraków University, the same year as his compatriot, the composer Mikołaj z Chrzanowa.
While archaic in style, they show the influence of the Franco-Flemish school, and are a rare early example of four-voice polyphony in Poland.
[4] Sebastian published a collection of his hymns in 1522 in Kraków, Aliquot hymni ecclesiastici, but no copies exist.
[1] His most popular was Opusculum musices (c. 1519), which was published in Kraków five years after theoretical treatises first appeared in Poland.
