Green pigments and mixtures
Artists' Materials
Green hues were obtained in a variety of ways: copper sulphates, copper carbonates as well as mixtures of azurite with lead-tin yellow and an organic yellow were identified. The individual artists seemed to favour one or more of these greens, which helps define their ‘signature’ palette.
Areas painted with copper sulphates were often found to contain high amounts of silicon. This may be due to the presence of quartz and other silicates, which would be naturally mixed with mineral copper sulphates.
Agony in the Garden (Passion according to St John)
The Master of the Dresden Prayer Book who painted this page was a remarkable storyteller. He captured both the essence of an event and the tenor of its setting. He constructed pictorial narratives rich in detail and pulsating with energy. The Fitzwilliam image conveys the breathless pace of the incidents unfolding before the viewer and builds suspense through the contrasting moods and actions of the protagonists. The central miniature shows Christ praying in the garden of Gethsemane. The historiated border depicts subsequent events: Christ addresses the Apostles, confirms his identity to the soldiers, and allows them to arrest him, while St Peter is about to cut Malchus’ ear.
The elaborate border with sequential narrative, integrated with the main image, the use of extreme foreshortening and of raised angle of vision to overcome the limitations of space and format are all characteristic of the final, most mature phase in this artist’s career. The novelty of his palette, including bright oranges, teals, burgundies, rich blues, and sometimes black, often arranged in surprising combinations, further attests to the refreshing originality of his art. To obtain such a wide range of colours, the Master of the Dresden Prayer Book made use of numerous pigments and a number of mixtures, including some which set him apart from the other artists who decorated this manuscript. He was the only one to include ultramarine blue in his palette in addition to azurite and indigo. He used the latter mainly in mixtures, to obtain grey and purple-brown hues, and mixed red lead with lead-tin yellow in orange areas.
