Bernardino Cirillo Franco (May 20, 1500 – June 19, 1575), also called Bernardino Cirillo and Cyrilo Franco, was a Roman Catholic bishop of Loreto, Italy.
His father was Pietro Sante de' Cirilli and his mother was Gemma Bucci.
[2] He participated in the Council of Trent and was interested in improving Church music.
[4] Cirillo attacked "modern" church music in a 1549 letter to Ugolino Gualteruzzi.
[1][5] In 1649, King John IV of Portugal wrote a treatise entitled Defense of modern music against the mistaken opinion of Bishop Cyrilo Franco [i.e., Bernardino Cirillo],[6] presenting a point-by-point rebuttal of Cirillo's letter.
