The Psalter-Hours of Isabelle of France
Prefatory cycle of full-page miniatures
Texts and Images
Presented as pairs on double openings, the six miniatures are painted on one side of the leaves, leaving the other side of the costly parchment blank. This is one of the numerous indications that no expense was spared in the production of this manuscript. Painted by a single artist (Hand A), the miniatures illustrate the end of David’s reign and the beginning of Solomon’s. Originally, there would have been more images, since the inventory of Charles V’s collection describes the manuscript as starting with numerous images (‘pluseurs histories au commencement’).
1
Detail of the red quadrilobe under magnification (16x). XRF analysis (below) allows the identification of gypsum (Ca, S) and an organic colourant (P, Al, K). The high amount of phosphorous may indicate that the dye was extracted from insects.
2
Detail of the folds in the tan-coloured robe under magnification (20x). The dark blue colour of the folds was obtained with indigo.
3
Detail of the brown hat under magnification (60), showing blue, orange and translucent red particles in a white matrix. FORS and XRF analyses identified the components of this complex mixture as indigo, red lead, an organic red and possibly lead white.
4
The XRF spectrum (above) of the green wall reveals the presence of a copper-based pigment, which also contains chlorine (Cl). The shape of the reflectance spectrum (below) allows the identification of verdigris, a pigment with variable composition which in this case includes copper chlorides.
