Biquardus
 Biquardus (also Wiquardus Giquardus and Guiquardus) (fl. c. 1440 – 1450) was a composer most likely from the Picardy province of France. Three of his works can be found in the St. Emmeram Choirbook although they may simply be contrafacta (new text to old music). These are In excelsis te laudant Ave stella matutina and Resurexit victor mortis.
