San Millán Beatus

The San Millán Beatus is an illuminated manuscript now held in the Royal Academy of History in Madrid as Cod.

Its illuminations are incomplete, but its text is one of the most complete surviving copies of the commentary.

The first seems to have been in the Province of Leon at the end of the 10th century - this created the core of the text and most of the miniatures.

The second phase occurred at the Monastery of San Millán de la Cogolla in La Rioja, probably at the end of the 11th century - this added colour to the existing miniatures and produced one new miniature.

John Williams argues that the second phase miniatures show influences from the Romanesque style and 12th-century French illumination and so date to the start of the first quarter of the 12th century.
