Borlet
Died: 1409
Borlet was a 14th- and 15th-century composer whose life we know extremely little about. It is thought that his name is an anagram of Trebol, a French composer who served Martin of Aragon in 1409 at the same time as Gacian Reyneau and other composers in the Codex Chantilly.
If this Trebol is the same as Trebor then he has six surviving compositions.
