Guillaume de Machaut survived the Black Death and decades of military campaigns, then wrote a self-aware romance about a nineteen-year-old fan who falls for him because he is famous. Born around 1300 near Reims, he served as secretary to the restless King John of Bohemia from 1323 to 1346, drafting correspondence in military camps across Europe while collecting church canonries in Verdun, Arras, and Reims. This episode explains how those benefices funded his mobility and how travel built his musical vocabulary.

We follow what happened after the blind King John died at Crecy in 1346 and Machaut became Europe’s most sought-after free agent, serving Bonne of Luxembourg, Jean de Berry, and Charles II of Navarre. We explore the Ars Nova and mensural notation, his layered motets combining sacred Latin with secular French, his codification of the lai, virelai, ballade, and rondeau, the Messe de Nostre Dame and the scholarly debate over whether it was conceived as a unified cycle, his metafictional Le Voir Dit, and his unprecedented decision to index and organize his own manuscripts before his death in 1377.

• Why a 14th-century canonry functioned as a passive income stream rather than a pastoral job
• How new notation let a composer in Paris send exact rhythms to a choir in Prague
• The possibility that Machaut and Chaucer crossed paths at 1359 treaty negotiations
• How Cypriot nobles used his Prise d’Alexandrie at banquets
• Why his secretarial background made him one of the first composers to curate his own legacy
