Egidius (Chantilly Codex composer) explained

Egidius, sometimes Magister Egidius, (c. 1350-1400?) is an ars subtilior composer found in the Chantilly Codex and the Modena Codex. Works attributed to "Egidius" in the Chantilly Codex comprise the ballades Roses et lis^[1] and Courtois et sage, dedicated to Pope Clement VII in Avignon.^[2] He is potentially identifiable with Egidius de Murino, a composer and music theorist active at the same time.^[3]

Egidius de Aurelia (Egidius of Orleans), composer of "Alma Polis / Axe poli cum artica" is thought to be a different composer.
