What is "egidius"

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 and Courtois et sage, dedicated to Pope Clement VII in Avignon. He is potentially identifiable with Egidius de Murino, a composer and music theorist active at the same time.

Egidius was a bishop of Reims in the 6th century and a nobleman from Austrasia. He was a supporter of king Childebert II. In 575 beside Rauching, Bertefred and others was his regent.
