Black Hours of Galeazzo Maria Sforza

The book used to be the property of Galeazzo Maria Sforza, the fifth Duke of Milan.

It is identified by some with the Black Hours of Charles the Bold that is mentioned in contemporary records, but others disagree.

The text is inscribed in gold and silver, using textus semi-quadratus, a Gothic script.

[1] According to the historian Antoine de Schryver, this manuscript was commissioned by Charles the Bold, duke of Burgundy, and is the one mentioned in the archives of the duke, decorated by the French illuminator Philippe de Mazerolles.

This hypothesis is criticized by other historians of art, who consider the Black Hours of Charles the Bold to be mostly lost, with fragments surviving in the Louvre (MI1091) and the Bibliothèque nationale de France (NAL149).
