Yellow and orange pigments

Artists' Materials

Technical analyses revealed the presence of realgar, lead-tin yellow type I, an organic yellow and an ochre rich in clay minerals. The same clay-rich ochre was also used to paint orange and brown passages on some folios. The presence of a yellow lead oxide, such as massicot, is also possible, and is especially likely in the miniature on fol. 36r.

The Annunciation miniature is surrounded by a full historiated border showing God addressing Moses from the Burning Bush and Moses receiving the Tablets of the Law. The central miniature is the work of the Painter of Additional 15677, while one of his most talented associates painted the border.
