French composer. Probably worked before 1378 at the court of John I of Aragon at Barcelona (where he was known as 'Lo Begue' and is not to be confused with Jacomi the bagpiper who was there 1372-1404). In 1378 he accompanied the Duke of Gerona to Flanders; in 1379 he was at the court of Castile and in 1383 was harpist to Cardinal Pedro de Luna. He was again at the Aragon court between 1391 and 1395. His surviving music consists of two virelais and four very complex ballades.
