Graduale oesa, Proprium de tempore, pars aestivalis
Description
The second volume of the three-part so-called "Wettinger Graduale",
made in Cologne for a cloister of Augustinian hermits, transferred
from Zurich to the Cistercian cloister of Wettingen after the
Reformation. The illuminated initials in this second volume are the
work of the "Younger Master of the Gradual" (Willehalm-Meister).
