The festivities of the Order of the Golden Fleece in Prague and Landshut in June 1585 have already attracted much attention among historians. This article considers the musical part of the celebration that has yet not been discussed in detail.
Using extant narrative, iconographical and musical sources, it focuses on the first part of the festivity which took place at Prague Castle. It postulates a hypothesis that the forty-part motet Ecce beatam lucem from the Mantuan composer and instrumentalist Alessandro Striggio (1536/37-1592) based on the text of German musician and poet Paulus Melissus-Schede (1539-1602) was performed in St.
Vitus' cathedral.
