Two leaves from two monumental Breviaries, in Latin, decorated manuscripts on parchment [France, first half of twelfth century (probably second quarter)] Two vast leaves, both double column, up to 38 lines in two good early gothic bookhands, music in neumes arranged around a red C-clef line, rubrics and simple initials in red, larger initials in elaborate blue and red strokes, with stylised penwork acanthus leaves in contrasting colour, perhaps from the same volume or set of volumes (approximately same size, and with the column with music on one matching in width with those of the other leaf, but foliated in different places by two different medieval hands), one leaf with part of inner border torn away, the other darkened and folded from use in a later binding, both approximately 370 by 265 mm.
