Most of the movements feature pairs of mensuration canons. The interval separating the two voices in each canon grows successively in each consecutive movement, beginning at the unison, proceeding to the second, then the third, and so forth, reaching the octave at the "Osanna" section in the Sanctus. The four voices each sing in a different ...

In particular, canon tables, with Evangelist portraits , are very important for the study of the development of manuscript painting in the earliest part of the Early Medieval period, where very few manuscripts survive, and even the most ...
