Solage (or Soulage), possibly Jean So(u)lage (fl. late 14th century) was a French composer, and probably also a poet. He composed the most pieces in the Chantilly Codex, the principal source of music of the ars subtilior, the manneristic compositional school centered on Avignon at the end of the century. Nothing is known about Solage's life, beyond what can be inferred from the texts to his music. Even his name is a puzzle. One possibility is that the single name "Solage" is a nickname or pseudonym
