Francis of Assisi, the famous merchant’s son and later founder of a religious order, has served as a source of inspiration from the most varied perspectives, and Damijan Mocnik has added to this tradition. The Slovenian composer and choral director composed a cantata in 2013 on the 25th anniversary of the D iocesan Grammar School in Ljubljana, based on the text of the famous Canticle of the Sun, and later (2014 16) using the cantata’s themes a complete setting of the ordinary of the mass as well. The instrumental parts match both the version for four-part mixed chorus (Carus 28.008/00) and the version for upper voices (Carus 28.008/50).
