See notes...A hand-size book. A graduale. Written in square notation, very neat. Sequentiary begins 236v, following Kyriale.A new quire begins 236, 236r vacat. 130 x 171 282 ff. Catalogue says saecula XIV. If it is 14th c, it is late. I judge the date to be early 15th century, but that could be off by 50 yrs in either direction. Many Dominican sequences: no 3, 6, 9, 10, 13 yet some eastern pieces. important source.
