1550, Carniola, Holy Roman Empire – 18/07/1591, Prague, Bohemia
Late-Renaissance composer of presumed Slovene ethnicity. Gallus's name has been Slovenianized as Jakob Petelin. Gallus most likely was educated at the Cistercian Stična Abbey in Carniola. He left Carniola sometime between 1564 and 1566, traveling first to Austria, and later to Bohemia, Moravia and Silesia. For some time he lived at the Benedictine Melk Abbey in Lower Austria. He was a member of the Viennese court chapel in 1574, and was choirmaster (Kapellmeister) to the bishop of Olomouc between 1579 (or 1580) and 1585. From 1585 to his death he worked in Prague as organist to the Church of St. John on the Balustrade. Gallus represented the Counter-Reformation in Bohemia, mixing the polyphonic style of the High Renaissance Franco-Flemish School with the style of the Venetian School. His output was both sacred and secular, and hugely prolific: over 500 works have been attributed to him. Some are for large forces, with multiple choirs of up to 24 independent parts.
