11th century "church musical manuscript" features Mozarabic plainchant

A recent blog entry for the BibliOdyssey website offers a close-up look at the amazing Visigothic Antiphonal, an 11th century church document packed with hymns, illuminations and circular calendars.

From the website:

The text is in Latin (although there's a definite Spanish "flavour" running through it to my ear/eye) and Visigothic musical notations are found throughout the three hundred folio leaves. Those musical notes have remained mostly indecipherable despite the manuscript attracting intense academic interest because of its unique status as the earliest most complete Mozarabic chant book in existence. Things may possibly improve on this front as a consequence of an international multidisciplinary symposium held last month in León devoted to the Visigothic antiphonal.
