The highly probable identification of the chapel singer
Johan Robert with Trebor, the composer, allows to relate several items of the Chantilly
Codex with John I of Aragon and his second wife, Yolande of Bar. Their court displayed a
significant role of musical patronage at the very end of the Middle Ages.
