Two pages from a print gradual, re-purposed as the covers of a notebook (probably after the 1966 flooding of Florence.)
As trimmed, 360 x 215 mm, including a 15mm folded-over edge on 3 sides. Written area 330x 200.
Red staves with black square notation. Diamond-shaped neumes for some unaccented syllables, and a "flipped" virga connecting some neumes.
Printed text uses ct ligatures and long s; likely 18th century, though recorded by the seller as 17th.
