The Hours of Isabella Stuart

Modelling of draperies

Artists' Techniques

Fabrics are modelled with highlights progressing from white mixed into the base pigment to pure white, and shaded with darker tones of the base pigment or with translucent glazes. Fully blended, directional brush strokes are combined with tiny brush strokes or dots. The resulting effect is most fluid and subtle in the images painted by the Madonna Master.

Detail of Gabriel’s purplish-blue sleeve under magnification (20x), showing extensive underdrawing visible through the thin paint layers. The drawing contributes to the definition of the sleeve’s folds, as do the short, parallel dark purple brushstrokes painted on the surface.

Annunciation (Hours of the Virgin, Matins)

The Annunciation, the standard image for the Hours of the Virgin, is set within an elaborate architectural structure and surrounded by a rich pictorial narrative in the border medallions. Starting from the top left and going anticlockwise, they show God the Father sending the dove of the Holy Spirit towards the Virgin, Joachim and Ann making an offering in the hope for a child, their meeting at the Golden Gate, the Virgin’s birth, her Presentation in the Temple, her Marriage to Joseph, and finally, on the top right, the Virgin at her loom.

The rounded faces with beady eyes (hotspots 1 and 2) and the gold clouds drifting across the sky are among the Giac Master’s hallmarks. Also typical of this artist is the extensive underdrawing and frequent changes of mind at the painting stage (hotspots 1, 3 and 5; see also Infrared Layer).

The arms of Isabella Stuart have been added within the initial.
